Why Pvc Doctor Is Harder Than You Think
How a VC Can Affect Your Heart

PVCs are common and may be experienced by a variety of people without causing any problems. If they happen frequently, PVCs may weaken your heart and increase the chance of suffering from heart failure.

The rhythm of your heart is usually controlled by a bundle of nerve fibers situated in the upper right part of your heart. This is known as the sinoatrial node or SA. Electrical signals travel from there to the lower heart chambers, or ventricles.


Causes

PVCs happen when the electrical impulse that normally initiates your heartbeat in a region known as the sinus node (also known as the sinoatrial node or SA node) does not. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat or feels like it's fluttering. They can happen infrequently and not cause any symptoms, but they may be frequent enough to affect your quality of life. Your doctor might prescribe medication when they occur frequently or cause weakness, dizziness or fatigue.

PVCs are generally harmless and don't increase your risk of heart disease. A lot of PVCs however, may weaken your heart muscle over time. This is especially relevant if they are triggered by a heart disease such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.

The signs of PVCs include a feeling that your heart beats slower or is fluttering, and you feel breathless. The fluttering can be more apparent when you exercise or consume certain drinks or foods. PVCs are more common in people with chronic stress or anxiety. Some medications, such as digoxin, amiodarone and cocaine, can increase the risk of developing PVCs.

If you have occasional PVCs, your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your physician may recommend that you avoid certain foods and drinks, like caffeine and alcohol. You can also lessen stress by taking enough rest and working out.

If you're suffering from a lot of PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. It destroys cells that cause PVCs. The procedure is carried out by a specialist known as an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms however it does not stop them from recurring in the future. In some cases, it can increase your risk of having atrial fibrillation (AFib), which can result in a stroke. This is rare however it could be life-threatening.

Signs and symptoms

Premature ventricular contracts, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats are harmless, but you may want to consult your doctor in the event of frequent heartbeats or if you notice symptoms such as dizziness or fatigue.

The electrical signals typically begin at the sinoatrial junction, located in the upper right portion of the heart. They travel down to the lower chambers (or ventricles) that pump blood. Then, the ventricles expand to push blood into your lungs and return to the heart to start the next cycle of pumping. But a PVC begins in a different location and is located in the bundle of fibers known as the Purkinje fibers in the bottom left portion of the heart.

When PVCs occur, they can make the heart pound or feel as if it skipped a beat. If you experience only a few episodes, and no other symptoms are present your cardiologist may not be able to treat you. If you have many PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter Monitor that records the heart's rhythm and count the number of PVCs.

Anyone who has had a previous heart attack or suffer from cardiomyopathy -which affects how the heart pumps bloodand should take their PVCs seriously and consult a cardiologist about lifestyle changes. These include avoiding alcohol, caffeine and smoking, reducing stress and anxiety, and getting enough rest. window doctors repairmywindowsanddoors.co.uk might prescribe medication to slow heartbeat, like a beta blocker.

Even if you don't have any other indications it is still recommended to have PVCs checked by a cardiologist if they happen often. These heartbeats that are irregular can be a sign of an issue with the structure of your heart or other health conditions, and over time, if they occur often enough, they may weaken the heart muscle. But the majority of people suffering from PVCs don't have any issues. They just want to be aware that the fluttering and skippy heartbeats aren't typical.

Diagnosis

PVCs may feel like fluttering or skipped heartbeats, particularly when they're intense or frequent. People who get lots of them may feel they're about to faint. Exercise can trigger them, but many athletes who suffer from these symptoms do not have heart or health problems. PVCs can be detected on tests such as an electrocardiogram or a Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart.

A doctor may be able to tell whether a person has PVCs from a history and physical examination. But sometimes they might not be aware of them until they examine the patient for other reasons, for instance after an accident or surgery. Ambulatory ECG monitors are able to detect PVCs, as well as other arrhythmias. They may be used to identify cardiac problems if there is any concern.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all you need. However, if your symptoms are causing discomfort or make you feel anxious, avoiding alcohol, caffeine and other decongestants as well as reducing stress levels can aid. Regular exercise, being 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 help manage these symptoms.

Treatment

If PVCs do not cause any symptoms or are not frequent, they usually don't need treatment. If they occur frequently, your doctor might want to check for heart problems or suggest lifestyle adjustments. You may also undergo an operation (called radiofrequency cathode ablation) to get rid them.

If you have PVCs, the electrical signal that causes your heartbeat starts somewhere different than the sinoatrial nerve (SA node) located in the upper right part of your heart. This could cause your heart to feel as if it skips a beating or has additional beats. It's not known what causes them, but they're more frequent in those with other heart issues. PVCs are more frequent as you age, and may occur more often during exercise.

If a patient experiences frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to determine if there is a structural heart problem. They will probably also do an exercise stress test to determine if the extra beats are a result of physical exercise. To determine whether there are any other causes for the increased beats, a heart catheterization or a cardiac MRI could be conducted.

The majority of people with PVCs don't experience any issues and can live a normal lifestyle. They can increase the risk of dangerous heart rhythm disorders particularly if they happen in certain patterns. In some instances, this means that the heart muscle becomes weaker and it is more difficult to pump blood throughout your body.

Regular exercise and a balanced diet will reduce your risk of developing PVCs. Avoid foods high in sodium and fat, and limit your consumption of tobacco and caffeine. It is also important to get enough sleep and manage stress. Certain medicines can also increase the risk of developing PVCs. So if you take one of these medicines, it's important to follow the doctor's advice regarding eating healthy, exercising and taking your medication.

In studies of patients with high PVC burdens (more than 20% of heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. This can result in the need for a transplant in certain individuals.
