How a VC Can Affect Your Heart

A lot of people experience occasional PVCs and have no issues. If they happen frequently, PVCs may weaken your heart and increase your risk of heart failure.

The heart's rhythm is controlled by a group of fibers that are located in the upper right part of your heart. This is known as the sinoatrial node, or SA. Electrical signals are transmitted to the ventricles or lower chambers of your heart.

Causes

PVCs are caused when the electrical impulse that normally begins your heartbeat in a part called the sinus node (also called the sinoatrial or SA Node) does not. Instead, the impulse begins in another area of your heart called the ventricles and triggers an untimed beat. These extra beats are also known as ventricular tachycardia and ventricular fibrillation. It may feel like the heart skipped a beating or feels like it is fluttering. They may happen rarely and cause no symptoms, or they can occur frequently enough to affect your daily 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 the risk of heart disease. In time, repeated PVCs can weaken the heart muscle. This is especially when the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.

The symptoms of PVCs include a feeling that your heart skips a beat or is fluttering, and you feel breathless. The fluttering could be more apparent when you exercise or have certain foods or drinks. People who suffer from chronic anxiety or stress may have more PVCs, and some drugs like amiodarone digoxin and cocaine can increase the likelihood of developing them.

If you are experiencing occasional PVCs your doctor may recommend lifestyle changes and medication. If they are a frequent occurrence, you may need to avoid some foods and beverages like caffeine and alcohol. You can also lessen stress by having enough sleep and exercising.

If you've got a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is usually successful in treating PVCs and reducing symptoms, but it does not stop them from recurring in the future. In some instances it can increase the risk of developing atrial fibrillation (AFib), which can result in a stroke. This isn't common however it could be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, can make your heart seem to flutter or skip the beat. These extra heartbeats can be harmless, but you may want to consult your doctor if they are frequent or if you notice symptoms such as dizziness or fatigue.

Normally, electrical signals begin in the sinoatrial node, located in the top right side of the heart. They travel down to the lower chambers (or ventricles) which pump blood. The ventricles expand to push the blood into the lung. They return to the heart's center to begin the next cycle of pumping. A pvc bifold doctor, visit the up coming document, starts in a different location, the Purkinje fibres bundle at the bottom left of the heart.

When PVCs occur and the heart is affected, it may feel as if it's beating faster or slower. If you experience only a few episodes, and there are no other symptoms your cardiologist may not be able to treat you. If you've got a lot of PVCs the doctor may recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat over the course of 24 hours. They may also recommend wearing a Holter Monitor, which records your heartbeat and tracks the number of PVCs.

People who have suffered a previous heart attack or cardiomyopathy, an illness that affects the method by which the heart pumps blood - should take their PVCs seriously and consult a cardiologist about lifestyle changes. These include cutting down on caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

If you are experiencing frequent PVCs even if do not have any other symptoms, you should consult an expert in cardiology. These irregular heartbeats could point to a problem with the structure of your heart or to other health conditions and, over time when they are frequent enough, they could weaken the heart muscle. The majority of people with PVCs do not experience any issues. They are interested in knowing if the 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 often might feel faint. Exercise can trigger them, but many athletes who experience them do not have heart or health problems. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors to record electrical signals from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to examine the heart and see how it's functioning.

A doctor may be able to identify if a person has PVCs from a history and physical examination. But sometimes they might only notice them while examining the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitors are able to detect PVCs, as well as other arrhythmias. They may be used to identify cardiac problems when there is a concern.

If your cardiologist finds that your heart is structurally normal, reassurance is the only treatment required. 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 and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms persist or severe, speak to your physician about the medications that could be able to reduce them.

Treatment

If PVCs aren't causing symptoms or occur rarely, they usually don't need treatment. If you have them often and frequently, your doctor might want to check for any other heart problems and suggest lifestyle changes or medicine. You could also have an operation to rid yourself of them (called radiofrequency catheter ablation).

If you have PVCs in your heart the electrical signal that causes your heartbeat begins somewhere other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. This can make it feel like your heart skips a beat or has extra beats. It's unclear what causes these symptoms, but they're common in people with other heart problems. PVCs can increase in frequency with age and might happen more frequently during exercise.

If a patient is experiencing frequent and painful PVCs, a physician should conduct an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely conduct an exercise stress test to determine if the increased heartbeats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study can be done to look for other reasons for the additional beats.

Most people with PVCs are not affected and can lead the normal life. However, they can increase your risk of having dangerous heart rhythm issues particularly if you have certain patterns of them. In some instances, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout your body.

A healthy, regular diet and a lot of exercise can reduce the risk of developing PVCs. Avoid foods high in sodium and fat, and limit your intake of tobacco and caffeine. It is also important to get enough sleep and reduce stress. Certain medications can increase your risk of PVCs. So if you take one of these drugs it's crucial to follow your doctor's instructions about a healthy diet, exercise and taking your medication.

Studies of patients who had a high burden of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. Some patients may require an organ transplant.
