How a VC Can Affect Your Heart

PVCs are common and may be experienced by many people without causing any problems. If they are frequent, PVCs may weaken your heart and increase your risk of heart failure.

The rhythm of your heart is usually controlled by a group of nerve fibers situated in the upper right-hand part of your heart. This is called 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 known as the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles and causes an irregular heartbeat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart skipped a beating or feels like it is fluttering. They may happen rarely and cause no symptoms, or they can occur frequently enough to affect your quality of life. If they occur frequently or cause weakness, dizziness or fatigue, your doctor may treat them with medicine.

For the majority of people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health problems. A lot of PVCs however, may weaken the heart muscle over time. This is especially relevant if they are triggered by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.

PVCs can cause symptoms, such as a sensation of your heart beating an beat, or the feeling of your heart fluttering. It is also possible to feel exhausted. The fluttering may be more evident when you exercise or consume certain foods or drinks. People who experience chronic anxiety or stress can have more PVCs, and some medications such as amiodarone, digoxin, and cocaine can increase the risk of developing them.

If you experience occasional PVCs your doctor might 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. double glazing doctor can also reduce stress by having enough sleep and working out.

If you've got a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells responsible for them. The procedure is carried out by a specialist, known as an electrophysiologist. The treatment is typically effective in treating PVCs and reducing symptoms, but does not prevent them from recurring 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.

Symptoms

Premature ventricular contractions or PVCs may cause your heart to skip or be fluttering. These extra heartbeats are harmless, but you might be advised to consult your physician in the event of frequent heartbeats or if you notice symptoms like dizziness, or fatigue.

Normally, electrical signals begin in the sinoatrial node, located in the top right portion of the heart, and move down to the lower chambers (or ventricles) that pump blood. The ventricles contract to pump blood into the lungs. They then return to the center to begin the next cycle of pumping. A PVC begins in a different place, the Purkinje fibres bundle in the bottom left of the heart.

When PVCs occur and the heart is affected, it may feel as if it's beating faster or slower. If you only have a few episodes, and there are no other symptoms, your cardiologist will probably not treat you. However, if you have large number of PVCs the doctor may recommend an electrocardiogram, or ECG, to measure your heart rate over 24 hours. The doctor may also recommend wearing a Holter monitor that records the heart's rhythm over time to determine how many PVCs you have.

People who have suffered a heart attack in the past or suffer from cardiomyopathy -which affects how the heart pumps blood should be aware of their PVCs and consult a cardiologist about lifestyle changes. This includes avoiding alcohol, caffeine and smoking, managing stress and anxiety, and getting enough rest. A cardiologist can also prescribe medication to slow the heartbeat, like a beta blocker.

If you are experiencing frequent PVCs even if you do not have other symptoms, you should consult a cardiologist. These heartbeats that are irregular could signal a problem with the structure of your lungs or heart, and if they occur often enough, it could weaken the heart muscle. But most people with PVCs don't experience any problems. They are interested in knowing if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can be felt as fluttering or skipped heartbeats, especially if they're frequent or intense. People who experience them often may feel faint. Exercise can trigger PVCs, but a lot of athletes who suffer from them have no heart or health issues. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. They have sensors which record electrical impulses that come from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to examine the heart and see how it's functioning.

A doctor may be able to determine if the patient is suffering from PVCs through a medical history and physical exam. Sometimes it is possible that they only be able to detect PVCs when they examine a patient for another reason, like following 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 cardiac disease.

If your cardiologist concludes that your heart is structurally normal, reassurance is the only remedy required. If your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine, and over the drug decongestants and decreasing stress can aid. Regular exercise, being at a healthy weight, and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms persist or extreme, consult your physician about the medications that could be able to control them.

Treatment

If PVCs aren't causing symptoms or occur rarely they aren't usually in need of treatment. If they are frequent, your doctor might want to check for heart conditions or recommend lifestyle changes. 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 causes your heartbeat begins somewhere other than at the sinoatrial (SA) node located in the upper right-hand corner of your heart. This can make it feel like your heart skips beats or is beating faster. It's not known what causes them, but they're more frequent in those with other heart problems. PVCs are more likely to occur as you age, and they could be more frequent during exercise.

If a patient has frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely perform an exercise stress test to determine if the additional heartbeats are related to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study could be conducted to determine other reasons for the additional beats.





The majority of people with PVCs do not experience any complications and can lead a normal lifestyle. However, they can increase your risk of having dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In certain cases, it means the heart muscle gets weaker and is unable to pump blood throughout your body.

A healthy, regular diet and a lot of exercise can help reduce your chances of developing PVCs. You should avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. Stress and sleep are also crucial. Certain medicines can also increase your risk of getting PVCs. If you are taking one of these medications it's crucial to follow your doctor's instructions about a healthy diet, exercise and taking your medication.

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