How a VC Can Affect Your Heart PVCs are common and may be experienced by a variety of people without causing any problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure. A bundle of fibers in the top right portion of your heart (the sinoatrial or SA node) usually controls your heart's rhythm. Electrical signals are transmitted to the ventricles, or lower chambers of the heart. Causes PVCs happen when the electrical impulse which normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. Instead, the impulse is generated in a different part of your heart, the ventricles, and causes an untimed beat. These extra beats, also called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or feels like it is fluttering. They can happen infrequently, causing no symptoms, but they could occur frequently enough to affect your quality of life. Your doctor may prescribe medicine in the event that they are frequent or cause weakness, dizziness or fatigue. PVCs are generally harmless and do not increase your risk of heart disease. Regular PVCs, however, can weaken the heart muscle over time. This is especially relevant if they are triggered by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure. The symptoms of PVCs include a feeling that your heart beats slower or it flutters. You may feel exhausted. The fluttering could be more noticeable when you exercise or have certain drinks or foods. People with chronic anxiety or stress can have more PVCs, and some drugs like amiodarone digoxin, and cocaine may increase the chance of developing them. If you are experiencing occasional PVCs, your doctor may recommend lifestyle changes and medicines. If you experience frequent PVCs, your physician may recommend avoiding certain foods and drinks, such as alcohol and caffeine. You can also lessen your stress levels by having enough sleep and working out. If you have a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells that are responsible for them. Electrophysiologists are the ones who perform this procedure. It is typically successful in treating the PVCs and reducing symptoms, but it doesn't stop them from occurring in the future. In certain cases it may increase the risk of developing atrial fibrillation (AFib) which can result in a stroke. It is not common but it could be life-threatening. Symptoms Premature ventricular contractions, also known as PVCs, can cause your heart appear to flutter or skip one beat. These extra heartbeats are generally harmless, however, you should talk to your doctor if you have frequent episodes or signs like dizziness or weakness. Normaly, electrical signals begin in the sinoatrial, located in the upper right corner of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. Then, the ventricles contract to propel the blood into your lungs and then return to the heart to begin the next cycle of pumping. A PVC starts at a different spot that is the Purkinje fibres bundle at the bottom left of the heart. When PVCs happen, the heart may feel as if it's skipping a beat or pounding. If you've experienced only a few episodes, but no other symptoms, the doctor probably won't be able to treat you. However, if you have large number of PVCs the doctor may recommend an electrocardiogram, also known as an ECG to gauge your heart rate over a 24-hour period. He or she might also suggest wearing a Holter Monitor which tracks the heart's rhythm and count the number of PVCs. Anyone who has suffered previously from a heart attack or cardiomyopathy – an illness that affects the heart's blood flow – should take their PVCs seriously and consult a cardiologist regarding lifestyle changes. These include abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist might prescribe medications to slow the heartbeat, like beta blockers. Even if you don't have any other symptoms however, you should have PVCs checked by an expert in cardiology if they occur often. These extra heartbeats may indicate a problem in the structure of your lungs or heart, and if they happen often enough, it could weaken the heart muscle. Most people with PVCs do not experience any problems. They just want to be aware that the fluttering or skippy heartbeats aren't typical. Diagnosis PVCs may feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who get lots of them might feel like they're going to faint. They can also occur during training, even though many athletes who get them don't have any problems with their health or heart. PVCs can be detected in tests like an electrocardiogram or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to look at the heart and determine how it's functioning. A doctor can often tell whether a patient has PVCs by looking at them and taking a medical history. Sometimes it is possible that they not be aware of PVCs until they examine a patient for another reason such as following an accident or surgical procedure. Ambulatory ECG monitors can detect PVCs and other arrhythmias. repairmywindowsanddoors can be used to identify cardiac problems if there is any reason to be concerned. If your cardiologist determines your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine, and other decongestants as well as reducing stress levels can help. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can also reduce your episodes of PVCs. If your symptoms continue or are extreme, talk to your doctor about medication options to treat these symptoms. Treatment If PVCs are rare or do not cause symptoms, they don't usually need treatment. If they are frequent, your doctor might be able to look for heart issues or suggest lifestyle adjustments. You may also undergo a procedure (called radiofrequency cathode ablation) to get rid them. When you have PVCs the electrical signal that causes your heartbeat starts somewhere other than the sinoatrial node (SA node) in the top right corner of your heart. This can make it feel like your heart skips a beat or has extra beats. They're more common among people suffering from heart disease however, it's not clear the reason behind them. PVCs are more frequent as you age, and may occur more often during exercises. If a patient is experiencing frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to see whether the additional beats are caused by physical exercise. To determine whether there are any other causes for the extra beatings, a heart catheterization or an MRI is possible. The majority of people who suffer from PVCs are not affected and live the normal life. However, they can increase the risk of developing dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some cases, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout the body. Regular exercise and a healthy diet can lower your risk of developing PVCs. You should avoid foods that are high in sodium and fat, and you should also limit caffeine and tobacco. Also, you should try to sleep enough and reduce stress. Certain medications can increase the risk of developing PVCs. If you are taking any of these medications it is essential to follow the advice of your doctor regarding eating a healthy diet and exercising as well as taking your medication. Studies of patients with a high amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can lead to the need for a heart transplant in a few people.
