Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block. Resting heart rates of less than 50 BPM are often normal ...
Excessive daytime sleepiness (EDS) is characterized by persistent sleepiness and often a general lack of energy, even during the day after apparently adequate or even prolonged nighttime sleep. EDS can be considered as a broad condition encompassing several sleep disorders where increased sleep is a symptom, or as a symptom of another ...

Symptoms. lightheadedness. dizziness. hypotension. vertigo. syncope. Diagnostic method. electrocardiogram. Sinus bradycardia is a sinus rhythm with a reduced rate of electrical discharge from the sinoatrial node, resulting in a bradycardia, a heart rate that is lower than the normal range (60–100 beats per minute for adult humans). [1][2]
Neurology. Irregular sleep–wake rhythm disorder (ISWRD) is a rare form of circadian rhythm sleep disorder. [2][3] It is characterized by numerous naps throughout the 24-hour period, no main nighttime sleep episode, and irregularity from day to day. [4] Affected individuals have no pattern of when they are awake or asleep, may have poor ...
The condition is generally diagnosed when a patient’s heart rate increases by at least 30 beats per minute (or 40 bpm in adolescents) within 10 minutes of standing, without a significant drop in ...
