How a VC Can Affect Your Heart

PVCs are common and can be experienced by a variety of people without causing any issues. However, if they happen 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 ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse that typically initiates your heartbeat at a point known as the sinus node (also known as the sinoatrial or SA node) isn't. The impulse actually begins in the ventricles and causes an irregular heartbeat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or feels like it's fluttering. They can happen infrequently and cause no symptoms, or they can occur frequently enough to affect your daily life. Your doctor may prescribe medicine when they occur frequently or cause dizziness, weakness or fatigue.

For the majority of people, PVCs are harmless and don't increase your risk of developing heart disease or other health issues. In time, frequent PVCs can weaken the heart muscle. This is especially when the PVCs are triggered by conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.

The signs of PVCs include a feeling that your heart skips a beat or it flutters. You may feel exhausted. The fluttering could be more evident when you exercise or consume certain drinks or foods. People with chronic anxiety or stress can have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the likelihood of developing them.

If you have occasional PVCs Your doctor may suggest lifestyle changes and medication. If you are prone to frequent PVCs, your doctor may recommend that you avoid certain foods and drinks such as alcohol and caffeine. You can also lower your stress by having enough sleep and exercising.

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. Electrophysiologists are the ones who carry out this procedure. It is typically 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 the risk of having atrial fibrillation (AFib) which is a condition that can result in stroke. It's not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions, or PVCs can cause your heart to skip or to flutter. These extra heartbeats are usually harmless, however, you should consult your physician when you experience frequent episodes or signs like dizziness or weakness.

Normally, electrical signals begin at the sinoatrial junction, which is in the top right-hand side of the heart. These signals move down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to pump blood into the lung. They then return to the center to start the next cycle of pumping. A Pvc Doctor starts at a different spot in the Purkinje fibers are located in the left side of the heart.

When PVCs happen they can make the heart appear to be racing or pounding. If you experience a few episodes and no other symptoms, your window & door doctor probably won't be able to treat you. If you've got a lot of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG, to measure the heart's rate over 24 hours. They might also recommend wearing a Holter monitor, which will record the heart's rhythm over time to see how many PVCs you have.

People who have suffered a heart attack in the past or have cardiomyopathy -which alters the way the heart pumps blood should be aware of their PVCs and talk to a cardiologist about changes to their lifestyle. Those include the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress and getting enough sleep. A cardiologist can prescribe beta blockers to slow the heartbeat.

If you experience frequent PVCs, even if you don't have any other symptoms, you should consult an expert in cardiology. These extra heartbeats may be a sign of a problem with the structure of your lungs or heart, and if they happen often enough, can weaken the heart muscle. However, most people suffering from PVCs do not experience any issues. They simply want to know that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs can be akin to heartbeats that are fluttering, particularly if they're frequent and intense. Patients who have a lot of them may feel they're going to faint. They can also happen with exercise, though many athletes who experience them don't have issues in their heart or health. PVCs may show up on tests such as an electrocardiogram or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.

A doctor will usually be able to determine whether a patient has PVCs by examining them and taking their medical history. Sometimes it is possible that they only notice PVCs when examining the patient for another reason, such as after an accident or surgical procedure. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias and could be utilized in the event of any suspicion of a cardiac condition.

If your cardiologist determines your heart is structurally healthy, reassurance could be all you need. However, if your symptoms are bothersome or cause you to feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress may help. Engaging in regular exercise, keeping at a healthy weight and drinking enough water can also help reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your doctor about medication that could help control them.

Treatment

If PVCs don't cause symptoms or are not frequent they aren't usually in need of treatment. If you have them often or frequently, your doctor may wish to check for other heart issues and recommend lifestyle changes or medications. You could also have a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node that is located in the upper right corner of your heart. This can cause your heart to feel like it skips beats or has extra beats. It's unclear what causes them, but they're more frequent in those with other heart conditions. PVCs may increase in frequency as you age, and they could be more frequent during exercising.

A physician should perform an ECG along with an echocardiogram on a patient that suffers from frequent and painful PVCs to identify structural heart conditions. They may also perform an exercise stress test to see whether the extra beats are caused by physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be done to look for other causes of the extra beats.

The majority of people who suffer from PVCs are not affected and live a normal life. They can increase your risk for dangerous heart rhythm disorders particularly if they develop in certain patterns. In certain cases, it means that the heart muscle becomes weaker and has trouble pumping blood through your body.

A regular, healthy diet and a lot of exercise can reduce your risk of developing PVCs. Avoid foods that are high in fat and sodium and limit your consumption of tobacco and caffeine. Also, you should try to get enough rest and manage stress. Certain medications can increase the risk of getting PVCs. So if you take one of these medications it is important to follow the door doctor's advice regarding eating healthy, exercising and taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of the total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. This can lead to the need for a heart transplant in some individuals.
