Why Its Important to See a Doctor Premature ventricular contractions PVCs are a form of irregular heartbeat These extra beats are typically not dangerous and can go away by themselves Doctors will monitor your heartbeat and check other vital indicators They might order an Holter monitor which tracks your hearts electrical impulses over a period of 24 to 48 hours They might also order blood tests to assess your electrolyte levels and thyroid hormones Diagnosis PVCs are caused by electrical impulses that misfire through the SA node a structure found in the lower chambers of the heart This causes the next heartbeat to be delayed leading to an experience similar to fluttering or skipped beats PVCs can occur in one pattern or repeated patterns Two consecutive PVCs are referred to as doublets whereas three or more consecutive PVCs constitute the condition known as ventricular tachycardia VT Some people are not experiencing any symptoms whereas others experience heart palpitations It can be felt as the sound of a beating heart or a slurred heartbeat Other common symptoms are tiredness or dizziness or a feeling of being unwell Many people with occasional PVCs dont require any treatment If someone is experiencing frequent episodes doctors may suggest a change in the way of life or diet including a reduction in caffeine alcohol and stress They may also prescribe medication such as betablockers and calcium channel blockers that can reduce the heart rate and lower blood pressure Doctors will ask about the medical history of the patient and do a physical exam to assess their general health They may also use an electrocardiogram ECG to capture a snapshot of the hearts electrical activity or a Holter monitor which is worn for longer durations and records the hearts rhythms over time In certain instances doctors may require blood tests to check for an electrolyte imbalance or drug toxicity Sometimes a pvc doctor will refer someone to a specialist for heart rhythm problems or an electrophysiologist for further evaluation This doctor can confirm the diagnosis of PVCs and determine whether they are benign or not PVCs are frequent and usually dont cause any issues unless they occur frequently over a long time This can cause weakening of the heart muscle or a condition known as pvcinduced cardiomyopathy This is more common in older adults or people suffering from heart disease It can also happen in healthy people with normal heart function but this is more likely for those who exercise regularly This is not a serious issue but you should consult your physician if you notice symptoms such as fatigue or fainting occur Treatment PVCs are not harmful and do not cause symptoms in a lot of people They do not require treatment However for those who do feel their heart has skipped a beat or is racing its vital to see a doctor as soon as possible A cardiologist will first interview you and conduct a physical examination listening to your heart with a stethoscope to detect any irregular beats You will also have an electrocardiogram ECG done that records the electrical signals in your heart and reveal any arrhythmias If an arrhythmia has been detected then the use of a portable ECG or 24hour Holter monitor will be required to document the irregular rhythm for longer periods of time These devices can help doctors determine whether you have PVCs and their cause like an imbalance in electrolytes toxic drugs or other causes An echocardiogram or an ultrasound of your heart could be ordered to determine whether your heart is healthy and look for any signs of structural problems that can lead to PVCs You may also be asked to undergo a stress test in order to find out the response of your heart to exercise Exercise can increase your frequency of PVCs You may also undergo blood tests to check your thyroid potassium and magnesium hormone levels to find out whether they are insufficient and can cause the development of PVCs If your doctor has confirmed that you have PVCs and has ruled any serious illnesses out the treatment option you choose depends on how they impact your life and how frequently they occur If they occur only occasionally and dont trigger any symptoms its unlikely that your doctor will recommend any medication to reduce their frequency or severity If you have frequent PVCs that cause palpitations or other symptoms such as feeling lightheaded or fainting your physician might prescribe medications like beta blockers and calcium channel blockers Altering your lifestyle to avoid triggers like smoking caffeine and excessive stress can also reduce the frequency of instances of these unusual pulses The following is a list of preventatives A person may experience no symptoms whatsoever from PVCs or feel heart palpitations irregular heartbeats that may be felt as skipped beats or fluttering in the chest Sometimes these episodes trigger an increase in pressure or fullness in the chest and other times they can make someone feel faint These episodes happen because the heart isnt pumping as efficiently as it normally does PVCs are linked to an increased risk of developing dilated cardiac myopathy This is a condition where the heart expands and becomes unable to pump blood PVCs often are caused by changes in the bodys chemical chemistry This can be caused by the release of thyroid hormones and adrenaline and alcohol consumption or caffeine Inactivity can trigger these symptoms as can stress or excess weight Some people can find that a change in diet helps reduce their PVCs For example they can avoid foods that contain preservatives that can cause disturbances in the heart rhythm such as disodium Guanylate E621 disodium inosinate E627 diazole sodium E282283 Eat more fruits and vegetables to ensure that you get sufficient magnesium It is important to get regular health checks which include yearly physicals and lab tests These tests can help identify any heart issues that could be causing your PVCs Also you should adhere to an appropriate diet and avoid smoking which could increase the frequency of your episodes A survey of healthcare professionals on 14 wards of a normal hospital found that they were mostly aware of the preventive measures to avoid vascular catheterassociated infections however their selfassessment of compliance with these practices was not great After window doctor compliance improved on some areas but was still very low This suggests that training is needed on how to implement preventive measures and those wards that are not than compliant should be targeted for monitoring of infection This information can then be used to guide the implementation of further quality improvement initiatives on these wards This will likely involve additional education and training for staff It will also be important to ensure that the right materials for implementing the preventive measures are in place Signs and symptoms If you feel that your heart is skipping beats or fluttering it could be a sign of premature ventricular contractions These arrhythmias may be harmless but they could indicate you have serious heart problems In healthy individuals PVCs that occur occasionally are not a problem They generally disappear by themselves If youve got many of them it could cause dizziness or weakening If youre worried about them consult your doctor about the symptoms You might be required to provide your medical history and they may also conduct an examination to determine the cause They might also conduct an electrocardiogram or other tests An ECG is a quick test that lets your health care provider see the signal from your heartbeat as it moves through your heart in a short duration The test will show whether you have PVCs Your doctor may also decide to conduct a 24 or 48hour Holter monitor which records your heartbeat for longer periods of time This can help distinguish PVCs from other types of arrhythmias that cause heart palpitations You can wear an event monitor a handheld device that records your heart rhythm for 30 days Other tests for the heart may be required based on the cause of your PVCs For instance a cardiologist could check your blood pressure and also perform an ultrasound of your heart echocardiogram These tests will determine whether you have an issue like heart failure or mitral valve prolapse or cardiomyopathy Your doctor may also need to conduct an analysis of your blood to determine the problem with your electrolytes For instance a low level of potassium levels or a high level of calcium This could be a sign of PVCs or other conditions that can cause them such as anemia and anxiety disorders You might be referred to an electrophysiologist an expert who specializes in treating heart rhythms that are abnormal If you have structural heart disease this specialist might need to do other tests such as an MRI or CT scan of your chest These tests can tell whether youve suffered damage to your heart and how serious it is In certain cases doctors may suggest a pacemaker to treat the condition which is causing the PVCs
