How a VC Can Affect Your Heart

Many people have occasional PVCs with no problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

The heart's rhythm is controlled by a group of nerve fibers situated in the upper right-hand part of your heart. This is called the sinoatrial node, or SA. Electrical signals travel to the ventricles or lower chambers of your heart.

Causes

PVCs are caused when the electrical impulse that normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. The impulse actually begins in the ventricles, causing a mistimed heartbeat. These extra beats, called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or feels like it's fluttering. They can occur infrequently and cause no symptoms, or they can happen often enough to interfere with your daily life. If they happen frequently or cause dizziness, weakness, or fatigue, your doctor may treat them with medication.

For most people, PVCs are harmless and do not increase the risk of developing heart disease or other health issues. Over time, frequent PVCs can weaken the heart muscle. This is particularly the case if they are caused by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

The signs of PVCs include a feeling that your heart beats faster or flutters, and you may feel exhausted. The fluttering could be more noticeable when you exercise or have certain foods or drinks. People with chronic stress or anxiety can have more PVCs, and some medications like amiodarone digoxin and cocaine can increase the chance of developing them.

If you have occasional PVCs your doctor may suggest lifestyle changes and medication. If you experience frequent PVCs, your physician may recommend that you avoid certain foods and drinks, such as alcohol and caffeine. You can also reduce your stress levels by getting enough sleep and working out.

If you have a lot of PVCs Your doctor might suggest a medical procedure called radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who carry out this procedure. The treatment is usually effective in treating PVCs and reducing symptoms, but it does not stop them from returning in the future. In certain instances, it can increase the risk of atrial fibrillation (AFib) which is a condition that can lead to stroke. This is rare, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, can make your heart seem to flutter or skip one beat. These heartbeats can be harmless, however, you should consult your physician when you experience frequent episodes or other symptoms such as dizziness or weakness.

Normally, electrical signals start at the sinoatrial junction, located in the upper right-hand side of the heart, and descend to the lower chambers (or ventricles) which pump blood. The ventricles contract to propel blood into the lungs, and then return to the heart to start the next cycle of pumping. But a PVC starts in a different location that is separate from the bundle of fibers called the Purkinje fibers, in the bottom left portion of the heart.

When PVCs occur, they make the heart beat or feel as if it skipped the beat. If you experience only a few episodes, but no other symptoms, the cardiologist probably won't treat you. But if you have a large number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, also known as an ECG, to measure your heartbeat over a 24-hour period. He or she might also recommend wearing a Holter monitor that will track the heart's rhythm over time, allowing you to see the number of PVCs you have.

If you've had a prior heart attack or have cardiomyopathy -an illness that affects the way that the heart pumps bloodand should be aware of their PVCs and consult a cardiologist about lifestyle changes. These include avoiding alcohol, caffeine and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist can prescribe medications to slow the heartbeat such as beta blockers.

Even if there aren't any other signs, you should still get PVCs examined by an cardiologist if they occur frequently. These extra heartbeats can point to problems with the structure of your heart or other health issues, and over time, when they happen frequently enough, they can weaken the heart muscle. However, most people with PVCs don't experience any problems. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs might be felt as fluttering or skipped heartbeats, especially when they are frequent or intense. People who experience them regularly may feel weak. They can also occur with training, even though many athletes who get them don't have issues with their health or heart. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses coming from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to look at the heart and observe how it's working.

A doctor will usually be able to determine the presence of PVCs by conducting a thorough examination and taking a medical history. But sometimes they might not be aware of them until they examine the patient for different reasons, like after a surgery or accident. double glazing doctor are able to detect PVCs, as well as other arrhythmias. They are able to detect heart disease if there is any reason to be concerned.

If your cardiologist determines your heart is structurally healthy, reassurance might be all you need. However, if your symptoms are bothersome or make you feel anxious, staying away from alcohol, caffeine and other decongestants and reducing stress can help. Getting regular exercise, staying at a healthy weight, and drinking enough fluids can reduce your episodes of PVCs. If your symptoms persist or are severe, speak with your physician about possible medications that can control these symptoms.

Treatment





If PVCs do not cause any symptoms or happen rarely, they usually don't need treatment. If you experience them frequently and frequently, your doctor might want to look for other heart issues and recommend lifestyle changes or medications. You could also undergo an operation (called radiofrequency cathode ablation) to get rid of them.

If you suffer from PVCs, the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial nerve (SA node) located in the upper right part of your heart. This can make it feel like your heart skips a beat or has extra beats. It's not known what causes them, but they're more common in people who have other heart problems. PVCs can become more frequent as you age, and they may be more frequent during exercising.

A doctor should perform an ECG and an echocardiogram on a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. They should also conduct an exercise stress test to determine if the extra beats are caused by physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study could be performed to find other reasons for the increased beats.

Most people with PVCs do not experience any issues and can live an ordinary life. They could increase the risk of dangerous heart rhythm disorders particularly if they happen in certain patterns. In some instances, this means that your heart muscle gets weaker and has trouble pumping blood throughout your body.

Regular exercise and a healthy diet can lower the chances of developing PVCs. Avoid foods high in fat and sodium and limit your intake of caffeine and tobacco. Sleep and stress are also crucial. Some medicines can also increase your risk of PVCs. If you are taking one of these medications it's crucial to follow your doctor's instructions about eating well, exercising and taking your medication.

Studies of patients suffering from 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. Some people may need a heart transplant.
