How a VC Can Affect Your Heart Many people have occasional PVCs and have no issues However if they happen frequently PVCs can weaken your heart muscle and increase your risk of heart failure The hearts rhythm is controlled by a group of fibers located in the upper right part of your heart This is called the sinoatrial node or SA Electrical signals travel to the lower heart chambers or ventricles Causes PVCs occur when the electrical impulse that usually starts your heartbeat at a point called the sinus node also called the sinoatrial or SA Node isnt Instead the impulse starts in a different area of your heart the ventricles and causes a wrongly timed beat These extra beats called ventricular tachycardia or fibrillation may feel like your heart skipped a beat or it feels like it is like its fluttering They may occur infrequently causing no symptoms but they can occur frequently enough to affect your quality of life If they occur frequently or cause dizziness weakness or fatigue your doctor could treat them with medicine For most people PVCs are harmless and do not increase the risk of heart disease or other health problems Over time frequent PVCs can weaken the heart muscle This is especially the case if they are caused by a heart disease such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure PVCs can cause symptoms like a feeling of your heart racing one beat or even the feeling of your heart fluttering You might also feel breathless The fluttering could be more apparent when you exercise or consume certain drinks or foods People who experience chronic anxiety or stress can have more PVCs and certain medications like amiodarone digoxin and cocaine can increase the risk of developing them If you experience occasional PVCs your doctor may suggest lifestyle changes and medication If they are a regular occurrence you may have to stay clear of certain drinks and foods like caffeine and alcohol You can also take steps to reduce your stress and get plenty of sleep and exercise If youre experiencing lots of PVCs The doctor may suggest a medical procedure called radiofrequency catheter ablation It destroys the cells that are responsible for PVCs The procedure is carried out by a specialist called an electrophysiologist It is typically effective in treating PVCs and reducing symptoms however it doesnt prevent them from occurring in the future In some cases it can increase your risk of atrial fibrillation AFib which can result in a stroke It is not common but it could be lifethreatening Symptoms Premature ventricular contractions also known as PVCs may make your heart appear to flutter or skip the beat These extra heartbeats can be harmless but you might be advised to consult your physician when they occur frequently or if you notice symptoms like dizziness or fatigue Normally electrical signals start in the sinoatrial node located in the top righthand side of the heart These signals move down to the lower chambers or ventricles which pump blood The ventricles then expand to push blood into your lungs and then return to the heart to start the next cycle of pumping But a PVC begins at a different spot from the bundle of fibers called the Purkinje fibers in the lower left part of the heart When window doctors occur they can make the heart pound or feel as if it skipped the beat If you have only just a few episodes and no other symptoms are present the cardiologist will likely not treat you If you have many PVCs the doctor may recommend that you undergo an electrocardiogram ECG to determine the heartbeat for a period of 24 hours The doctor may also recommend wearing a Holter Monitor which tracks your heartbeat and tracks the number of PVCs If youve had a previous heart attack or suffer from cardiomyopathy an illness that affects how the heart pumps blood and must be aware of their PVCs and consult a cardiologist about changes to their lifestyle These include abstaining from alcohol caffeine and smoking managing stress and anxiety and getting enough rest A cardiologist may also prescribe medication to slow heartbeat like beta blockers If you experience frequent PVCs even if do not have other symptoms you should see a cardiologist These extra heartbeats can be a sign of an issue with the structure of your heart or other health issues and over time when they happen frequently enough they may weaken the heart muscle Most people with PVCs dont experience any issues They want to know if the irregular heartbeats or fluttering is normal Diagnosis PVCs may appear to be fluttering or skip heartbeats especially if theyre frequent or intense People who experience them regularly may feel faint They can also occur with exercising but most athletes who suffer from them dont have issues in their heart or health PVCs can be detected on tests such as an electrocardiogram or Holter monitor These use sticky patches with sensors on them to record electrical impulses coming from your heart A cardiologist might also use an echocardiogram which uses ultrasound to look at the heart and determine how its working A doctor can often tell the presence of PVCs by conducting a thorough examination and taking a medical history However sometimes they will not be aware of them until they examine the patient for other reasons such as following an accident or surgery Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias They are able to detect cardiac disease when there is a reason to be concerned If your cardiologist finds that your hearts structure is normal reassurance will be the only treatment needed If your symptoms are causing you discomfort or make you feel anxious staying away from alcohol caffeine and overthe drug decongestants and reducing stress may aid Getting regular exercise staying at a healthy weight and drinking enough water can help reduce the frequency of PVCs If your symptoms continue or are extreme talk with your physician about possible medication options to treat the symptoms Treatment If PVCs arent common or dont cause symptoms they dont usually require treatment If you have them often or frequently your doctor may wish to examine for other heart conditions and recommend lifestyle changes or medicine You may also undergo an operation called radiofrequency cathode ablation to eliminate them If you suffer from PVCs in your heart the electrical signal that creates your heartbeat is located outside of the sinoatrial SA node which is located in the upper right corner of your heart This can make it feel like your heart skips a beat or is beating faster PVCs are more prevalent among people with heart problems but its not known the reason behind them PVCs may increase in frequency as you age and could be more frequent during exercises A physician should perform an ECG along with an echocardiogram on a patient who has frequent and painful PVCs to rule out structural heart diseases The doctor will also likely perform an exercise stress test to determine if the increased heartbeats are due to physical exercise A heart catheterization cardiac MRI or nuclear perfusion studies can be conducted to determine other reasons for the increased beats The majority of people with PVCs do not have any issues and can lead the normal life They can increase the risk of developing heart rhythm disorders that can be dangerous particularly if they develop in certain patterns In some instances this means the heart muscle gets weaker and is having difficulty pumping blood through your body A healthy regular diet and a lot of exercise can reduce your risk of developing PVCs You should avoid foods that are high in fat and sodium and reduce your intake of caffeine and tobacco You should also try to get enough sleep and manage stress Certain medicines can also increase the risk of developing PVCs If you are taking any of these medications it is important that you follow your doctors advice regarding eating a healthy diet exercising as well as taking your medication In studies of patients with PVC burdens that are excessive more than 20 of total heartbeats there was a higher incidence of arrhythmiainduced cardiac myopathy was found Some patients may require a heart transplant
