These extra beats are usually not harmful and will disappear on their own. To determine PVC doctors listen to your heartbeat and look for other vital signs. They may order a Holter Monitor that records the electrical impulses of your heart over a time of 24 to 48 hours. They can also request blood tests to determine your electrolyte levels and thyroid hormones. Diagnosis PVCs occur when electrical impulses from the heart's lower chambers ventricles, or lower chambers, fail to pass through a structure known as the SA node. This delay the next heartbeat which can cause a feeling of skipped beats or fluttering in the chest. PVCs can occur in isolation or in repeated patterns. Two consecutive PVCs are referred to as doublets, whereas three or more consecutive PVCs constitute ventricular tachycardia (VT). Some people don't experience any symptoms whatsoever Others experience heart palpitations which can feel like the heart beating faster or slower. Other common symptoms are tiredness, dizziness or a sensation of being sick. Many people who experience occasional PVCs don't require any treatment. If a person has frequent episodes, doctors may suggest a change to diet or lifestyle like limiting caffeine, alcohol and stress. They can prescribe medication such as beta-blockers and calcium channel blockers that lower blood pressure and slow the heart rate. Doctors will ask about the person's medical history and conduct a physical exam to assess their general health. They may also use an electrocardiogram (ECG) to get a snapshot of the heart's electrical activity or a Holter monitor, which is worn for longer durations and monitors the heart's rhythms over time. In certain cases doctors may require blood tests to check for an electrolyte imbalance or toxic effects from drugs. A pvc doctor might refe
