The term "relative bradycardia" can refer to a heart rate lower than expected in a particular disease state, often a febrile illness. [8] Chronotropic incompetence (CI) refers to an inadequate rise in heart rate during periods of increased demand, often due to exercise, and is an important sign of SND and an indication for pacemaker implantation.
This is complemented by gastro-coronary reflexes [12] whereby the coronary arteries constrict with "functional cardiovascular symptoms" similar to chest-pain on the left side and radiation to the left shoulder, dyspnea, sweating, up to angina pectoris-like attacks with extrasystoles, drop of blood pressure, and tachycardia (high heart rate) or ...

Reflex bradycardia is a bradycardia (decrease in heart rate) in response to the baroreceptor reflex, one of the body's homeostatic mechanisms for preventing abnormal increases in blood pressure. In the presence of high mean arterial pressure , the baroreceptor reflex produces a reflex bradycardia as a method of decreasing blood pressure by ...
Only a colonoscopy can tell doctors where tumors are located in the colon, or guide treatment. The location of colorectal tumors can determine whether patients need surgery, or chemotherapy and ...
[medical citation needed] Sinus bradycardia can also be an adaptive advantage; for example, diving seals may have a heart rate as low as 12 beats per minute, helping them to conserve oxygen during long dives. [4] Sinus bradycardia is a common condition found in both healthy individuals and those who are considered well-conditioned athletes. [5]
