How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people without causing any issues. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.

The rhythm of your heart is controlled by a bundle of fibers that are located in the upper right part of your heart. This is called the sinoatrial node, or SA. Electrical signals travel from there to the lower chambers of your heart or ventricles.

Causes

PVCs happen by the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. The impulse actually starts in the ventricles and causes an irregular heartbeat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. They may feel like the heart skipped a beat or feels fluttering. They can occur rarely, causing no symptoms, but they may occur frequently enough to affect your quality of living. If they are very frequent or cause dizziness, weakness, or fatigue, your doctor might treat them with medicine.

For the majority of people, PVCs are harmless and do not increase the risk of developing heart disease or other health problems. Regular PVCs however, may weaken the heart muscle over time. This is especially true if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.

PVCs can cause symptoms, such as a sensation of your heart skipping one beat, or even the feeling of your heart fluttering. You might also feel exhausted. The fluttering can be more apparent if you exercise, or consume certain drinks or foods. People who suffer from chronic anxiety or stress may have more PVCs, and some medications such as amiodarone, digoxin, and cocaine may increase the chance of developing them.

If you experience occasional PVCs your window & door doctor may suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to avoid certain foods and beverages, such as caffeine and alcohol. You can also reduce your stress and take advantage of plenty of rest and exercise.

If you're experiencing lots of PVCs The doctor may suggest a medical procedure called radiofrequency catheter ablation. This eliminates the cells that cause PVCs. Electrophysiologists are the ones who perform this procedure. It is usually successful in treating the PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In certain cases, it may increase the risk of atrial fibrillation (AFib) which is which can result in stroke. This is rare, 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 harmless, but you may need to see your doctor if they are frequent or if you notice symptoms such as dizziness or fatigue.

Normally, electrical signals start in the sinoatrial node, which is in the top right portion of the heart, and travel down to the lower chambers (or ventricles) which pump blood. The ventricles expand to force blood into the lungs. They return to the heart's center to begin the next cycle of pumping. But a PVC begins in a different place that is separate from the bundle of fibers known as the Purkinje fibers, located in the bottom left portion of the heart.

When PVCs happen and the heart is affected, it may appear to be skipping a beat or pounding. If you have only a few episodes, and there are no other symptoms your cardiologist may not be able to treat you. However, if you have large number of PVCs the doctor may suggest an electrocardiogram, or ECG, to measure your heart rate over the course of 24 hours. He or she might also recommend wearing a Holter monitor that records the heart's rhythm over time to determine the number of PVCs you have.

People who have suffered a previous heart attack or cardiomyopathy - an illness that affects way the heart pumps blood - should take their PVCs very seriously and consult a cardiologist about lifestyle changes. These include avoiding alcohol, caffeine and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe medications to slow heartbeat, for example, a beta blocker.

Even if there aren't any other signs it is still recommended to have PVCs examined by a cardiologist if they happen often. These irregular heartbeats could be a sign of problems with the structure of your heart or other health conditions and, over time when they are frequent enough, they may weaken the heart muscle. Most people who suffer from PVCs do not have any issues. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs may appear to be fluttering or skip heartbeats, especially when they're intense or frequent. People who experience them frequently might feel faint. Exercise can cause them, but many athletes who suffer from them do not have heart or health issues. PVCs could 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 may also use an ultrasound echocardiogram for examining the heart.

A double glazing doctor near me is often able to tell the presence of PVCs by looking at them and taking a medical history. However, sometimes they will only notice them while examining the patient for other reasons, such as after an accident or surgery. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias, and can be used if there's any concern of a cardiac condition.

If your cardiologist concludes that your heart is structurally normal, reassurance will be the only remedy required. If your symptoms are bothersome or make you feel anxious, staying away from alcohol, caffeine, and over the drug decongestants and the reduction of stress could aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all aid in reducing the frequency of PVCs. If your symptoms continue or are extreme, talk to your doctor about possible medications that can control them.

Treatment

If PVCs don't cause symptoms or happen rarely generally, they don't require treatment. If you are frequently affected, your doctor may want to examine for other heart conditions and recommend lifestyle changes or medication. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate of them.

When you have PVCs, the electrical signal that triggers your heartbeat begins somewhere different than the sinoatrial nerve (SA node) located in the upper right side of your heart. This could cause it to feel like your heart skips a beat or has a few extra beats. They're more common among people with heart problems, but it's not known the reason behind them. PVCs are more frequent as we age and can occur more often during exercise.

If a patient experiences frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to see whether the additional beats are a result of physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study could be performed to find other causes of the additional beats.

The majority of people who suffer from PVCs do not experience any problems and can enjoy a normal lifestyle. They could increase the risk of heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some instances, this means that the heart muscle becomes weaker and is having difficulty pumping blood through your body.

Regular exercise and a balanced diet can lower the chances of developing PVCs. Avoid foods high in fat and sodium, and limit your consumption of tobacco and caffeine. Sleep and stress are also crucial. Certain medicines can also increase your risk for PVCs. If you take any of these medications it is essential to follow your doctor's recommendations about eating healthy exercising, as well as taking your medication.

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