When one strains to increase the flow of urine, it stimulates the vagus nerve (usually more pronounced in elderly men with large prostates). The vagus nerve stimulus causes slowing down of the heart (bradycardia) and a drop in blood pressure. The heart cannot perform effectively as a pump because insufficient blood comes to it.
It can have many potential causes, including genetics, lifestyle habits, and underlying health issues. Some types of cardiovascular disease, such as some cardiomyopathies, develop due to factors ...
Often sinus node dysfunction produces no symptoms, especially early in the disease course. Signs and symptoms usually appear in more advanced disease and more than 50% of patients will present with syncope or transient near-fainting spells as well as bradycardias that are accompanied by rapid heart rhythms, referred to as tachycardia-bradycardia syndrome [4] [5] Other presenting signs or ...

[2] A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia.

Determining the cause of Roemheld syndrome is still not an exact science. If you have an ultrasound or sleep study, ensure that you know how to reproduce the symptoms, as it is difficult to detect any abnormalities when symptoms have subsided.
Causes range from non-serious to potentially fatal. [1] There are three broad categories of causes: heart or blood vessel related; reflex, also known as neurally mediated; and orthostatic hypotension.
