10 Pvc Doctor Tricks All Experts Recommend
How a VC Can Affect Your Heart

Many people have occasional PVCs and have no issues. If they occur often, PVCs may weaken your heart and increase the chance of suffering from heart failure.


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

Causes

PVCs occur when the electrical impulse that normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. They may feel like the heart skipped a beating or feels fluttering. They can happen infrequently and cause no symptoms, or they can happen often enough to affect your daily life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor could treat them with medication.

PVCs are generally safe and do not increase your risk of developing heart disease. Frequent PVCs however, could weaken your heart muscle over time. This is especially when the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.

The symptoms of PVCs include a feeling that your heart skips a beat or it flutters. You may feel exhausted. The fluttering may be more evident if you exercise, or consume certain beverages or foods. PVCs are more prevalent for those who suffer from chronic anxiety or stress. Certain medications, such as digoxin, amiodarone and cocaine, can increase the risk of developing PVCs.

If you are experiencing occasional PVCs, your doctor may suggest lifestyle changes and medication. If you are prone to frequent PVCs, your doctor might recommend that you avoid certain foods and drinks like caffeine and alcohol. You can also lower your stress by having enough sleep and working out.

If you're suffering from many PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation. It eliminates the cells that cause PVCs. This is done by a specialist, known as an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib), which can lead to stroke. It is not common however it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, can cause your heart seem to skip or flutter one beat. These heartbeats that are not normal can be harmless, however you might be advised to consult your physician in the event of frequent heartbeats or if you experience symptoms like dizziness, or fatigue.

The electrical signals typically begin in the sinoatrial node located in the upper right side of the heart. They travel down to the lower chambers (or ventricles) which pump blood. Then, the ventricles contract to propel blood into your lungs and return to the heart to start the next pumping cycle. However, a PVC starts in a different location and is located in the bundle of fibers known as the Purkinje fibers, located in the left-hand side of the heart.

When window doctors www.repairmywindowsanddoors.co.uk occur, they can make the heart beat or feel as if it skipped a beat. If you have just a few episodes but no other symptoms, the doctor probably won't be able to treat you. If you have many PVCs the doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. They might also recommend wearing a Holter monitor that will track your heartbeat over time to determine the number of 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 take their PVCs seriously and talk to an expert in cardiology about lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

Even if you don't have any other signs it is still recommended to have PVCs examined by an cardiologist if they occur often. These irregular heartbeats could point to an issue with the structure of your heart or to other health conditions and, over time when they are frequent enough, they can weaken the heart muscle. The majority of people with PVCs do not have any issues. They just want to know that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs may feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them often might feel faint. Exercise can cause them, but most athletes who suffer from them have no heart or health issues. PVCs can be detected in tests like an electrocardiogram, or Holter monitor. These use sticky patches with sensors on them to record electrical impulses coming from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to examine the heart and observe how it's functioning.

Often, a doctor will be able to identify if a person has PVCs from a patient's history and physical examination. Sometimes it is possible that they not be aware of PVCs until they examine a patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They can be used to detect heart disease if there is any 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 cause you to feel anxious, avoiding alcohol, caffeine and other decongestants as well as reducing stress levels can help. Regular exercise, being at a healthy weight, and drinking enough water can also decrease the likelihood of PVCs. If the symptoms persist or are severe, talk with your physician about possible medications that can control these symptoms.

Treatment

If PVCs do not cause any symptoms or are not frequent, they usually don't need treatment. If you have them often, your doctor may want to look for other heart conditions and suggest lifestyle changes or medicine. You could also have an operation (called radiofrequency cathode ablation) to eliminate them.

If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial (SA) node, which is located in the upper right corner of your heart. This could cause it to feel like your heart skips a beat or has extra beats. PVCs are more prevalent among people who suffer from heart issues however, it's not clear what causes them. PVCs are more likely to occur as you age, and might occur more frequently during exercising.

A doctor should perform an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to determine if there are structural heart problems. The doctor will also likely conduct an exercise stress test in order to determine if the increased heartbeats are caused by physical activity. To determine whether there are other reasons for the extra beats an invasive heart catheterization or an MRI could be conducted.

Most people who suffer from PVCs have no complications and can live an ordinary life. They could increase the risk of heart rhythm disorders that can be dangerous particularly if they happen in certain patterns. In some instances, this means that the heart muscle gets weaker and is unable to pump blood throughout your body.

A healthy, regular diet and regular exercise can reduce the chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your intake of caffeine and tobacco. You should also try to sleep enough and manage stress. Certain medicines can also increase the risk of developing PVCs. If you're taking one of these medications it's crucial to follow the doctor's advice about eating well, exercising and taking your medication.

Studies of patients suffering from an excessive amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can lead to the need for a heart transplant in some individuals.
