How a VC Can Affect Your Heart
PVCs are common and can be experienced by a wide range 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.
A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial or SA node) typically regulates the heart's rhythm. Electrical signals travel to lower heart chambers or ventricles.
Causes
PVCs are caused when the electrical impulse that typically initiates your heartbeat in a part known as the sinus node (also called the sinoatrial or SA node) isn't. Instead, the impulse starts in another area of your heart called the ventricles and triggers a mistimed beat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart beats faster or feels fluttering. They can occur rarely without causing any symptoms, but they may also happen frequently enough to affect your quality of life. Your doctor may prescribe medication if they are frequent or cause dizziness, weakness or fatigue.
For most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Over time, repeated PVCs can weaken the heart muscle. This is especially true if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can cause heart failure.
PVCs can trigger symptoms like a feeling of your heart racing one beat, or even the feeling of your heart fluttering. You might also feel exhausted. The fluttering could be more evident when you exercise or consume certain foods or drinks. People who experience chronic stress or anxiety can have more PVCs, and some medications like amiodarone digoxin, and cocaine may increase the risk of developing them.
If you experience occasional PVCs your doctor may recommend lifestyle changes and medication. If they are a frequent occurrence, you may need to avoid certain drinks and foods, such as caffeine and alcohol. You can also reduce stress by having enough sleep and exercising.
If you have many PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. Electrophysiologists are the ones who perform this procedure. The treatment is typically effective in treating PVCs and reducing symptoms, but does not prevent them from becoming recurring in the future. In certain cases, it may increase the risk of developing atrial fibrillation (AFib) which is which can result in stroke. It is not common, but it could be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs can cause your heart to skip or flutter. These extra heartbeats can be harmless, but you may 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 upper right-hand side of the heart. They move down to the lower chambers (or ventricles) which pump blood. Then, the ventricles contract to propel blood into the lungs, and then return to your heart and start the next cycle of pumping. A PVC begins at a different spot in the Purkinje fibers are located in the left-hand side of the heart.
When PVCs occur, they can make the heart pound or feel like it skipped one beat. If you have just a few episodes but no other symptoms, your doctor probably won't be able to treat you. But if you have a number of PVCs, the doctor may recommend an electrocardiogram, also known as an ECG, to measure the heart's rate over a 24-hour period. They may also recommend wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.
Anyone who has suffered previously from a heart attack or cardiomyopathy, an illness that affects the method by which the heart pumps blood - must take their PVCs seriously and consult a cardiologist regarding lifestyle changes. Those include abstaining from alcohol, caffeine and smoking, reducing stress and anxiety and getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.
If you experience frequent PVCs even if don't have any other signs, you should see an expert in cardiology. These irregular heartbeats could indicate an issue with the structure of your heart or other health conditions and, over time if they occur often enough, they can weaken the heart muscle. Most people with PVCs do not experience any problems. They simply want to be aware that the fluttering and skippy heartbeats aren't typical.
Diagnosis
PVCs may feel like heartbeats that are fluttering, particularly if they're frequent and intense. Patients who have a lot of them might feel like they're going to faint. They can also happen with exercise, though many athletes who suffer from them do not have any issues with their heart or health. 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 signals from your heart. A cardiologist may also use an ultrasound echocardiogram for examining the heart.
Most of the time, a doctor will be able to tell whether the patient has PVCs from a history and physical examination. Sometimes, however, they may not be aware of PVCs until they examine the patient for another reason such as following an accident or surgery. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They are able to identify cardiac problems if there is any concern.
If your cardiologist determines that your heart's structure is normal, reassurance will be the only treatment required. If your symptoms are bothersome or cause you to feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress can help. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all help to reduce the frequency of PVCs. If the symptoms persist or are severe, speak to your doctor about medication options to treat these symptoms.
Treatment
If PVCs do not cause any symptoms or are not frequent, they usually don't need treatment. If they occur frequently, your doctor might be able to look for heart issues or suggest lifestyle adjustments. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).
If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node located in the upper right corner of your heart. This could cause your heart to feel like it skips a beating or has extra beats. It's not clear what causes these symptoms, but they're common in people with other heart conditions. PVCs can increase in frequency as we age and can occur more often during exercising.
A doctor should perform an ECG and an echocardiogram on a patient that has frequent and painful PVCs to determine if there are structural heart problems. They should also conduct an exercise stress test to determine whether the additional beats are due to physical exercise. window doctors near me repairmywindowsanddoors , cardiac MRI or nuclear perfusion study can be performed to find other reasons for the increased beats.
The majority of people with PVCs are not affected and live the normal life. However, they may increase your risk of having dangerous heart rhythm issues, especially if you have certain patterns of them. In some cases this means that the heart muscle becomes weaker and has difficulty pumping blood throughout 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 caffeine and tobacco. It is also important to get enough sleep and manage stress. Certain medications can increase the risk of getting PVCs. If you take any of these medications, it is important to follow your doctor's recommendations regarding eating a healthy diet 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 myopathy in the heart was observed. Some people may need an organ transplant.
