How a VC Can Affect Your Heart PVCs are commonplace and can be experienced by a variety of people without causing any problems If they are frequent PVCs may weaken your heart and increase the risk of heart failure A bundle of fibers located in the upper righthand corner of your heart the sinoatrial or SA node usually controls your hearts rhythm Electrical signals travel to ventricles or lower chambers of the heart Causes PVCs are caused when the electrical impulse that normally starts your heartbeat in a region called the sinus node also known as the sinoatrial or SA Node does not The impulse actually starts in the ventricles which causes an untimed heartbeat These extra beats also known as ventricular tachycardia or ventricular fibrillation can feel like your heart skipped a beat or feels fluttering They can occur infrequently and not cause any symptoms or they can happen often enough to impact your daily life Your doctor might prescribe medication if they are frequent or cause dizziness weakness or fatigue In most people PVCs are harmless and dont increase your risk of developing heart disease or other health problems Over time repeated PVCs can weaken the heart muscle This is particularly true if the PVCs are triggered by conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can cause heart failure The symptoms of PVCs include feeling like your heart beats faster or flutters and you may feel exhausted The fluttering may be more noticeable when you exercise or have certain drinks or food items PVCs are more prevalent in those suffering from chronic anxiety or stress Some medications such as digoxin amiodarone and cocaine can increase the risk If you have occasional PVCs Your doctor might suggest lifestyle changes and medications If they are a regular occurrence you may have to stay clear of certain foods and beverages such as alcohol and caffeine You can also reduce stress by taking enough rest and working out If you have lots of PVCs he may suggest a medical treatment called radiofrequency catheter ablation This eliminates the cells that cause PVCs This is done by a specialist known as an electrophysiologist It is usually effective in treating PVCs and reducing symptoms however it doesnt prevent them from recurring in the future In some cases it can increase the risk of developing atrial fibrillation AFib which can cause a stroke This isnt common however it could be lifethreatening Signs and symptoms Premature ventricular contractions or PVCs may make your heart seem to skip or flutter one beat These heartbeats can be harmless but you should consult your physician when you experience frequent episodes or symptoms like dizziness or weakness The electrical signals typically begin in the sinoatrial node located in the top right portion of the heart These signals descend to the lower chambers or ventricles which pump blood The ventricles then contract to push the blood into the lungs They then return to the center to begin the next cycle of pumping A PVC starts at a different spot that is the Purkinje fibers are located in the lefthand side of the heart When PVCs occur they can make the heart beat faster or feel as if it skipped one beat If you only have just a few episodes and there are no other symptoms your cardiologist may not treat you If you have a lot of PVCs your doctor may recommend that you undergo an electrocardiogram ECG to determine the heartbeat for 24 hours He or she might also recommend wearing a Holter Monitor that records your heartbeat and tracks the number of PVCs Anyone who has had a prior heart attack or suffer from cardiomyopathy a condition that affects the way that the heart pumps blood and should be aware of their PVCs and speak with a cardiologist about lifestyle changes Those include the avoidance of alcohol caffeine and smoking reducing stress and anxiety and getting enough rest A cardiologist may prescribe beta blockers to slow down the heartbeat Even if you dont have any other signs however you should have PVCs checked by a cardiologist if they happen frequently These irregular heartbeats could point to problems with the structure of your heart or to other health conditions and over time if they occur often enough they could weaken the heart muscle The majority of people with PVCs dont experience any problems They just want to be aware that the fluttering and racing heartbeats arent normal Diagnosis PVCs might be felt as fluttering or skipped heartbeats particularly when they are frequent or intense People who experience them often may feel weak They can also occur with training even though many athletes who experience them do not have any issues in their heart or health PVCs may show up in tests like an electrocardiogram ECG or Holter monitor They have sensors which record electrical impulses that come from your heart A cardiologist can also perform an ultrasound echocardiogram to study the heart A doctor will usually be able to determine if a patient has PVCs by examining them and taking their medical history Sometimes it is possible that they not be aware of PVCs until they examine a patient for another reason such as after an accident or a surgery Ambulatory ECG monitors can detect PVCs as well as other arrhythmias They may be used to detect cardiac disease if there is any concerns If your cardiologist has determined that your heart is structurally healthy reassurance could be all you need If your symptoms are bothersome or cause you to feel anxious avoiding caffeine alcohol and overthecounter decongestants as well as reducing stress levels can aid Regular exercise and maintaining a healthy weight and drinking enough fluids can all aid in reducing the frequency of PVCs If your symptoms persist or are severe speak to your doctor about medications that can control the symptoms Treatment If PVCs arent causing symptoms or occur rarely they arent usually in need of treatment If they are frequent your doctor might be able to look for heart conditions or recommend lifestyle adjustments You may also undergo an operation to rid yourself of them called radiofrequency catheter ablation If you have PVCs the electrical signal that causes your heartbeat is generated from a place different than the sinoatrial nerve SA node located in the upper right corner of your heart It can feel like your heart skips beats or is beating faster PVCs are more frequent among those with heart problems but its not known what causes them PVCs are more likely to occur as you age and could be more frequent during exercising If a patient experiences frequent and painful PVCs doctors should perform an ECG and an echocardiogram to determine if there is a structural heart problem pvc doctor will also likely perform an exercise stress test to determine if the increased heartbeats are caused by physical exercise To find out whether there are any other causes for the extra beats an invasive heart catheterization or cardiac MRI could be conducted Most people with PVCs dont experience any problems and can enjoy a normal lifestyle They can increase your risk for heart rhythm disorders that can be dangerous particularly if they happen in certain patterns In some instances this means the heart muscle gets weaker and is having difficulty pumping blood through your body A regular healthy diet and regular exercise can help reduce your risk of developing PVCs Avoid foods high in fat and sodium and limit your intake of caffeine and tobacco Sleep and stress are also crucial Certain medicines can also increase the risk of getting PVCs If you are taking one of these medications it is important to follow the doctors advice about eating well exercising and taking your medication In studies of patients with PVC burdens that are high more than 20 of the total heartbeats a higher rate arrhythmiainduced cardiac myopathy was discovered This can result in a need for a heart transplant in certain individuals
