[1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
A resting heart rate of 100 beats per minute or an increase in heart rate of 100 beats per minute with minimal exertion; Excluding any potential secondary causes of sinus tachycardia; Ruling out atrial tachycardias; Palpitations or presyncope (or both) symptoms that have been clearly linked to resting or easily induced sinus tachycardia.
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]

Among those who are hospitalized, rates are between 1% and 2.5%. [2] It is associated with an increased mortality, whether due to hyperkalaemia itself or as a marker of severe illness, especially in those without chronic kidney disease. [8] [7] The word hyperkalemia comes from hyper-'high' + kalium 'potassium' + -emia 'blood condition'. [9] [10]
