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).
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.
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 ...
There are four types of sensations: Extra-systolic (premature heartbeats), Tachycardic (rapid heart rate), Anxiety-related or Intense palpitations. Anxiety-related palpitations are the most common. [1] [3] They often happen due to stress or psychological factors. We must evaluate patients to tell apart harmless causes from serious heart issues.
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]
Further research is needed, the results of this review were applicable mainly to older individuals with moderate to high cardiovascular risk. [ 16 ] In 2019, a systematic review of anti-hypertensive treatment trials in elderly patients with isolated systolic hypertension demonstrated results with the intensive decrease of SBP to <140 mm Hg.
