A faster heart rate may occur in response to stimuli such as stress, excitement, exercise, or caffeine intake.
While an increased heart rate is usually a normal physiological response, it can sometimes indicate heart disease or other health problems.
A slower heart rate may result from issues with the heart's electrical signals or heart muscle problems.
Bradycardia can cause palpitations because the heart may not pump enough blood, leading to insufficient oxygen and nutrients for the body.
An irregular heart rhythm, often due to issues with the heart's electrical signals, can cause arrhythmias.
Arrhythmias may be triggered by various factors, including heart disease, electrolyte imbalances, and medication side effects.
The heart may need to work harder to pump blood, possibly due to heart conditions like valve disease or cardiomyopathy.
An increased cardiac load can lead to palpitations as the heart's beating becomes more pronounced.
Slight changes in the heart's position can also lead to palpitations, as the sensation of the heart beating may become more noticeable.
