How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by many people with no cause for concern. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

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

Causes

PVCs are caused when the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) is not initiated. Instead, the impulse starts in another area of your heart called the ventricles and triggers a mistimed beat. These extra beats, called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat or is like it's fluttering. They can occur rarely without causing any symptoms, but they may also happen frequently enough to affect your quality of life. If they happen frequently or cause weakness, dizziness or fatigue, your doctor may treat them with medicine.

In most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Over time, frequent PVCs can weaken the heart muscle. This is especially relevant if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.

The symptoms of PVCs include feeling like your heart skips a beat or is fluttering, and you feel breathless. The fluttering can be more evident if you exercise, or consume certain beverages or foods. People with chronic anxiety or stress can have more PVCs, and some medications like amiodarone digoxin, and cocaine can increase the chance of developing them.

If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medications. If you have frequent PVCs, your doctor might recommend that you avoid certain foods and drinks, such as caffeine and alcohol. You can also lower stress by taking enough rest and exercising.

If you have lots of PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. This is done by a specialist called 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 cases, it can increase your risk of having atrial fibrillation (AFib) which could cause a 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 generally harmless, however, you should talk to your doctor if you have frequent episodes or other symptoms such as dizziness or weakness.

The normal electrical signals start in the sinoatrial area, which is located in the upper right-hand corner of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles then contract to pump blood into the lungs. They return to the center to begin the next cycle of pumping. A pvc doctor (just click the next document) starts at a different spot in the Purkinje fibres bundle in the bottom left of the heart.

When PVCs occur and the heart is affected, it may appear to be racing or pounding. If you experience only just a few episodes and no other symptoms are present your cardiologist may not treat you. But if you have a large number of PVCs the doctor may recommend an electrocardiogram, also known as an ECG, to measure your heartbeat over 24 hours. The doctor may also recommend wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.

People who have suffered an earlier heart attack or have suffered from cardiomyopathy - a condition which affects the way the heart pumps blood - should take their PVCs seriously and consult an expert in cardiology about lifestyle changes. This includes abstaining from alcohol, caffeine and smoking, managing anxiety and stress, and getting enough rest. A cardiologist might prescribe medications to slow the heartbeat for example, a beta blocker.

If you experience frequent PVCs, even if you don't have any other symptoms, you should consult a cardiologist. These heartbeats that are irregular can be a sign of problems with the structure of your heart or other health issues and, over time, if they occur often enough, they may weaken the heart muscle. Most people who suffer from PVCs do not experience any issues. They simply want to be aware that the door doctor fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs might feel like fluttering or skipped heartbeats, particularly when they are frequent or intense. People who get lots of them may feel they're about to faint. Exercise can trigger them, but most athletes who suffer from these symptoms do not have heart or health problems. PVCs can be detected on tests such as an electrocardiogram or Holter monitor. These are sticky patches that have sensors on them to record electrical impulses from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to examine the heart and observe how it's working.

Most of the time, a doctor will be able to tell whether the double glazing doctor patient is suffering from PVCs from a patient's history and physical examination. Sometimes it is possible that they only notice PVCs when examining patients for a different reason, such as after an accident or surgery. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias, and could be utilized in the event of any suspicion of a cardiac condition.

If your cardiologist determines that your heart is structurally normal, reassurance will be the only treatment required. If your symptoms are causing discomfort or make you feel anxious, staying away from alcohol, caffeine door and window doctor other decongestants as well as reducing stress levels can help. Getting regular exercise, staying at a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms persist or are extreme, talk with your physician about possible treatments that could help control them.

Treatment

If PVCs aren't causing symptoms or are not frequent they aren't usually in need of treatment. If they happen frequently, your doctor might need to examine for heart conditions or recommend lifestyle changes. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere other than at 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 not clear what causes these symptoms, but they're common in people who have other heart conditions. PVCs are more frequent as we age and can occur more often during exercises.

A physician should perform an ECG along with an echocardiogram for a patient who has frequent and painful PVCs to identify structural heart conditions. The doctor may also perform an exercise stress test in order to determine if the extra heartbeats are caused by physical exercise. To find out whether there are any other causes for the extra beats the heart catheterization or an MRI can be performed.

The majority of people with PVCs do not experience any issues and can live a normal lifestyle. However, they can increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In some instances, this means the heart muscle gets weaker and has trouble pumping blood throughout your body.

A healthy, regular diet and a lot of exercise can reduce the chances of developing PVCs. Avoid foods that are high in sodium and fat and limit caffeine and tobacco. You should also try to get enough rest and reduce stress. Certain medicines can also increase your risk of getting PVCs. If you are taking one of these medications, it's important to follow the doctor's advice about a healthy diet, exercise and taking your medication.

In studies of patients suffering from PVC burdens that are high (more than 20% of the total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. This could lead to the need for a transplant in some people.
