How a VC Can Affect Your Heart

PVCs are common and may be experienced by a variety of people with no cause for concern. But if they occur frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.

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

Causes

PVCs occur when the electrical impulse that typically starts your heartbeat in a part known as the sinus node (also known as the sinoatrial or SA node) isn't. Instead, the impulse starts in a different part of your heart--the ventricles--and causes a mistimed beat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart beats faster or feels fluttering. They can happen infrequently and not cause any symptoms, but they could also happen frequently enough to impact your quality of living. Your doctor may prescribe medication in the event that they are frequent or cause weakness, dizziness or fatigue.

For most people, PVCs are harmless and do not increase the risk of heart disease or other health problems. Regular PVCs however, could weaken the heart muscle over time. This is particularly true if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.

PVCs can trigger symptoms like a feeling of your heart racing one beat, or even fluttering. It is also possible to feel exhausted. The fluttering can be more apparent when you exercise or consume certain foods or replace broken window glass drinks. PVCs are more common in those suffering from chronic anxiety or stress. Some medications, such as digoxin, amiodarone and cocaine, may increase the risk.

If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your doctor might recommend that you avoid certain foods and drinks like caffeine and alcohol. You can also reduce your stress and take advantage of plenty of rest and historic window Repair exercise.

If you've got a lot of PVCs Your doctor may suggest a medical procedure called radiofrequency catheter ablation. It eliminates the cells that are responsible for them. The procedure is carried out by a specialist, known as an electrophysiologist. The treatment is generally successful in treating PVCs and reducing symptoms, but it does not stop them from returning in the future. In some instances it can increase your risk of atrial fibrillation (AFib) which can lead to a stroke. It is not common, but it could be life-threatening.

Symptoms

Premature ventricular contracts or PVCs may cause your heart to skip or flutter. These extra heartbeats are harmless, but you might need to see your doctor if they are frequent or if you notice symptoms like dizziness or fatigue.

The electrical signals normally begin in the sinoatrial, located in the upper right part of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. The ventricles contract to propel blood into the lungs, and return to the heart to start the next cycle of pumping. A PVC starts in a different place that is the Purkinje fibres bundle at the bottom left of the heart.

When PVCs occur, the heart may feel as if it's racing or pounding. If you experience only a few episodes, but no other symptoms, the doctor probably won't be able to treat you. If you've got a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. The doctor may also recommend wearing a Holter Monitor which tracks your heartbeat and tracks the number of PVCs.

If you've had previously from a heart attack or cardiomyopathy - an illness that affects way the heart pumps blood - should take their PVCs seriously and speak to a cardiologist regarding lifestyle changes. Those include the avoidance of alcohol, caffeine, and smoking, reducing anxiety and stress, and getting enough sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you have frequent PVCs even if you do not have other symptoms, you should consult a cardiologist. These heartbeats that are irregular can point to an issue with the structure of your heart or to other health conditions, and over time, if they occur often enough, they can weaken the heart muscle. However, most people suffering from PVCs don't have any issues. They want to know if the fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs might be felt as fluttering or skipped heartbeats, particularly when they're intense or frequent. People who experience them regularly may feel faint. Exercise can trigger PVCs, but a lot of athletes who experience these symptoms do not have heart or health problems. PVCs may show up on tests such as an electrocardiogram or a Holter monitor. These use sticky patches with sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.

A doctor will usually be able to determine whether a patient has PVCs by looking at them and taking a medical history. Sometimes however, they might only be able to detect PVCs when they examine a patient for another reason such as following an accident or surgical procedure. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias, and they might be used when there is a concern of heart disease.

If your cardiologist concludes that your heart is structurally normal, reassurance will be the only treatment required. However, if your symptoms are troubling or cause you to feel anxious, staying away from 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 reduce your episodes of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your doctor about medications that could be able to control the symptoms.

Treatment

If PVCs do not cause any symptoms or happen rarely generally, they don't require treatment. If you have them often, your doctor may want to examine for other heart conditions and recommend lifestyle changes or medicine. You may also undergo a procedure (called radiofrequency cathode ablation) to get rid of them.

If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located other than at the sinoatrial (SA) node that is located in the upper right corner of your heart. This could cause your heart to feel as if it skips beats or has extra beats. PVCs are more frequent among those suffering from heart disease however, it's not clear what causes them. PVCs can increase in frequency as we age and can occur more often during exercises.

If a patient is experiencing frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out structural heart disease. The doctor will also perform an exercise stress test to determine if the increased heartbeats are caused by physical exercise. To determine whether there are other reasons for the extra beatings the heart catheterization or cardiac MRI could be conducted.

The majority of people with PVCs have no complications and can lead a normal life. However, they may increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In some instances, this means that the heart muscle becomes weaker and is unable to pump blood through your body.

Regular exercise and a healthy diet can reduce your risk of developing PVCs. You should avoid foods that are high in fat and sodium and restrict your intake of tobacco and caffeine. Stress and sleep are also important. Certain medications can increase the risk of developing PVCs. If you are taking any of these medications it is crucial that you follow the advice of your doctor about eating healthy and exercising as well as taking your medication.

Studies of patients with a high burden of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This could lead to the need for a heart transplant in a few patients.
