Szívverése

Szívverése is a Hungarian word that translates to "heartbeat" or "pulse" in English. It refers to the rhythmic contraction and expansion of the heart, which pumps blood throughout the body. The normal resting heart rate for adults is typically between 60 and 100 beats per minute. This rate can increase during physical activity, stress, or excitement, and decrease during sleep or relaxation.

The cardiac cycle, which encompasses one heartbeat, consists of two main phases: systole and diastole. During systole, the heart muscle contracts, pushing blood out into the arteries. Diastole is the relaxation phase, where the heart chambers fill with blood in preparation for the next contraction. The sounds associated with a heartbeat, often described as "lub-dub," are produced by the closing of the heart valves.

Monitoring one's szívverése is important for assessing cardiovascular health. Deviations from the normal range, such as tachycardia (a heart rate that is too fast) or bradycardia (a heart rate that is too slow), can be indicative of underlying medical conditions. Irregular heartbeats, known as arrhythmias, can also occur. Doctors often measure pulse rate and rhythm as part of a routine physical examination.
