Most SVTs are unpleasant rather than life-threatening, although very fast heart rates can be problematic for those with underlying ischemic heart disease, or the elderly. Episodes can be treated when they occur by Valsalva maneuver , adenosine injection or taking a AV node blocking agent as pill-in-pocket, but regular medication may also be ...
The cause is not known. [3] Risk factors include alcohol, psychostimulants such as caffeine, nicotine, and amphetamines, psychological stress, and Wolff-Parkinson-White syndrome, which often is inherited. [3] The underlying mechanism typically involves an accessory pathway that results in re-entry. [3]
Stress ulceration is a single or multiple fundic mucosal ulcers that causes upper gastrointestinal bleeding, and develops during the severe physiologic stress of serious illness.

Also, it can be a normal variant or artifacts, such as: Pseudo-ST-depression, which is a wandering baseline due to poor skin contact of the electrode [3]
Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system.Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis, and hyperthermia.

The symptoms of anxiety and depression disorders can be very similar. A diagnosis of mixed anxiety–depressive disorder as opposed to a diagnosis of depression or an anxiety disorder can be difficult. Due to this, it has long been a struggle to find a singular set of criteria to use in the diagnosis of mixed-anxiety depressive disorder. [3]
