Although there are many possible symptoms associated with PVCs, PVCs may also have no symptoms at all. PVCs may be perceived as a skipped heart beat, a strong beat, palpitations, or lightheadedness. They may also cause chest pain, a faint feeling, fatigue, or hyperventilation after exercise. [2] Symptoms may be more pronounced at times of stress.
Your heart rate is the number of times your heart pump beats per minute to do its job, which is to circulate blood (to provide oxygen and nutrients) to the rest of the body, says Puja Mehta, M.D ...
In otherwise healthy patients, occasional single premature atrial contractions are a common finding and most of times do not indicate any particular health risk. Rarely, in patients with other underlying structural heart problems, PACs can trigger a more serious arrhythmia such as atrial flutter or atrial fibrillation. [10]
A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...
The winter months are sometimes referred to as “heart attack season,” and there may actually be science to support this claim. Lifespan reported that factors such as barometric pressure ...
Arrhythmias, also known as cardiac arrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. [2] A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia.

They are often described as a skipped beat, a rapid flutter, or a pounding in the chest or neck. [1] [2] Palpitations are not always the result of a physical problem with the heart and can be linked to anxiety. [3] However, they may signal a fast or irregular heartbeat. Palpitations can be brief or long-lasting. They can be intermittent or ...
Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).
