The cold water can cause heart attack due to severe vasoconstriction, [2] where the heart has to work harder to pump the same volume of blood throughout the arteries. For people with pre-existing cardiovascular disease , the additional workload can result in myocardial infarction and/or acute heart failure , which ultimately may lead to a ...
Septic shock can be caused by Gram negative bacteria such as (among others) Escherichia coli, Proteus species, Klebsiella pneumoniae (which have an endotoxin on their surface that produces adverse biochemical, immunological and occasionally neurological effects which are harmful to the body), other Gram-positive cocci, such as pneumococci and ...
Certain endocrine disorders such as pheochromocytoma can also cause epinephrine release and can result in tachycardia independent of nervous system stimulation. Hyperthyroidism can also cause tachycardia. [15] The upper limit of normal rate for sinus tachycardia is thought to be 220 bpm minus age. [citation needed]
POTS symptoms can be caused by several things, but the underlying issue is that POTS patients' bodies have a harder time pushing blood back up toward their heart and brain after sitting or lying ...
Tachycardia that is not sinus tachycardia usually results from the addition of abnormal impulses to the normal cardiac cycle.

[citation needed]
Some patients who experience shortness of breath, wheezing, coughing, swelling and palpitations may assume their symptoms are linked to a cold when these could be signs of heart failure, she said ...
The underlying causes of sudden cardiac arrest can result from cardiac and non-cardiac etiologies. The most common underlying causes are different, depending on the patient's age. Common cardiac causes include coronary artery disease, non-atherosclerotic coronary artery abnormalities, structural heart damage, and inherited arrhythmias. Common ...
Why does Long COVID cause POTS? Based on the literature from 2023, the current understanding is that the COVID-19 virus may trigger several problems:. Autoimmunity: The SARS-CoV-2 virus can cause ...
