How a VC Can Affect Your Heart

Many people experience occasional PVCs with no problems. If they happen frequently, PVCs may weaken your heart and increase the risk for heart failure.

A bundle of fibers located in the upper right part of your heart (the sinoatrial or SA node) typically regulates your heart's rhythm. Electrical signals travel from there to the lower chambers of your heart, or ventricles.

Causes

PVCs happen when the electrical impulse that typically begins your heartbeat in a part called the sinus node (also called the sinoatrial or SA node) does not. Instead, the impulse is generated in a different area of your heart--the ventricles--and causes a mistimed beat. These extra beats, window And door doctor also known as ventricular tachycardia, or ventricular fibrillation, may feel like your heart skipped a beat or feels like it is fluttering. They can occur rarely without causing any symptoms, but they may be frequent enough to affect your standard of life. Your doctor might prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.

For the majority of people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Regular PVCs however, may weaken the heart muscle over time. This is particularly relevant if the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure.

The symptoms of PVCs include feeling like your heart beats faster or it flutters. You may feel exhausted. The fluttering could be more noticeable when you exercise or consume certain foods or beverages. People who suffer from chronic stress or anxiety can have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the chance of developing them.

If you experience occasional PVCs, your doctor may recommend lifestyle changes and medicines. If you are prone to frequent PVCs, your doctor may suggest that you stay away from certain foods and drinks, such as alcohol and caffeine. You can also reduce your stress, and make sure you get enough sleep and exercise.

If you've got a lot of PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells responsible for them. This is done by a specialist known as an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In some instances it may increase your risk of having atrial fibrillation (AFib), which can cause a stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions, or PVCs can cause your heart to skip or to flutter. These extra heartbeats are harmless, however you might need to see your doctor when they occur frequently or if you experience symptoms such as dizziness or fatigue.

The electrical signals typically begin at the sinoatrial junction, located in the top right portion of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to push the blood into the lung. They then return to the center to start the next cycle of pumping. However, a PVC begins in a different location, from the bundle of fibers known as the Purkinje fibers, located in the bottom left portion of the heart.

When PVCs occur, they make the heart beat or feel like it skipped one beat. If you experience only one or two episodes, and there are no other symptoms the cardiologist will likely not treat you. If you have many PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. They may also suggest wearing a Holter Monitor, which records your heart rhythm and counts the number of PVCs.

If you've had a prior heart attack or suffer from cardiomyopathy -an illness that alters the way the heart pumps blood must be aware of their PVCs and speak with a cardiologist about changes to their lifestyle. These include avoiding caffeine, alcohol and smoking, managing anxiety and stress, and ensuring adequate sleep. A cardiologist may prescribe beta blockers to slow the heartbeat.

If you experience frequent PVCs even if do not have any other symptoms, you should consult a cardiologist. These heartbeats that are irregular could indicate a problem in the structure of your heart or lungs, and if they occur frequently enough, can weaken your heart muscle. Most people with PVCs do not have any problems. They want to know if the fluttering heartbeats or skipping heartbeats is normal.

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 about to faint. Exercise can cause PVCs, but a lot of athletes who suffer from them have no heart or health issues. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.

A doctor is often able to tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes however, they might only notice PVCs when examining the patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to identify cardiac problems in the event of any reason to be concerned.

If your cardiologist finds that your heart's structure is normal, reassurance is the only remedy required. If your symptoms are causing you discomfort, or cause you to be anxious, avoiding alcohol, caffeine and other over the drug decongestants and reducing stress may aid. Getting regular exercise, staying at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If your symptoms are persistent or extreme, consult your doctor about medication that could be able to reduce them.

Treatment

If PVCs are rare or don't cause symptoms, they don't usually require treatment. If you have them often and frequently, your doctor might want to check for other heart conditions and suggest lifestyle changes or medications. You might also get an intervention to get rid of them (called radiofrequency catheter ablation).

If you suffer from PVCs The electrical signal that triggers your heartbeat starts somewhere other than the sinoatrial node (SA node) in the top right part of your heart. This could cause your heart to feel like it skips beats or has extra beats. PVCs are more prevalent among people suffering from heart disease, but it's not known what causes them. PVCs are more likely to occur as you age, and could be more frequent during exercise.

If a patient has frequent and painful PVCs, a physician should conduct an ECG window and door doctor near me an echocardiogram to rule out structural heart disease. The doctor will also conduct an exercise stress test in order to determine if the additional heartbeats are due to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study can be conducted to determine other causes of the additional beats.

Most people with PVCs have no complications and can lead a normal life. They may increase your risk for heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some cases this means that the heart muscle becomes weaker and it is more difficult to pump blood throughout your body.

Regular exercise and a healthy diet can reduce your chances of developing PVCs. Avoid foods high in sodium and fat, and limit your consumption of caffeine and tobacco. Sleep and stress are equally crucial. Some medicines may also increase your risk of getting PVCs. If you are taking any of these medications it is crucial that you follow your doctor's recommendations about eating healthy, exercising, and taking your medication.

In studies of patients with pvc doctor burdens that are excessive (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. Some patients may require an organ transplant.
