Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
Taking (prolonged) pulse may result in a rhythm that seems irregular. Electrocardiography and laser Doppler imaging [3] allow to visualize Premature heart beats. From their appearance, their location can be assessed. The Holter monitor allows to quantify them, to specify their characteristics and their repetition.
[table-of-contents] stripped. Whether brought on by stress, physical activity, or an extra cup of joe in the morning, most of us have all felt our heart rate quicken at one time or another.However ...
Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.

Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2]
The pulse is the rate at which the heart beats while pumping blood through the arteries, recorded as beats per minute (bpm). [11] It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. [11] The pulse is commonly taken at the wrist (radial ...
Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats. [1] It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis.
