During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5] Vagal maneuvers, or a procedure known as catheter ablation, may be effective in certain types. [5]
Paroxysmal supraventricular tachycardia (PSVT) is a type of supraventricular tachycardia, named for its intermittent episodes of abrupt onset and termination. [3] [6] Often people have no symptoms. [1] Otherwise symptoms may include palpitations, feeling lightheaded, sweating, shortness of breath, and chest pain. [2] The cause is not known. [3]
An episode of supraventricular tachycardia due to AVNRT can be terminated by any action that transiently blocks the AV node. Some of those with AVNRT may be able to stop their attack by using physical manoeuvres that increase the activity of the vagus nerve on the heart, specifically on the atrioventricular node.
SVT is recognized by the presence of pain, warmth, redness, and tenderness over a superficial vein. [1] The SVT may present as a "cord-like" structure upon palpation. [1] The affected vein may be hard along its entire length. [2] SVTs tend to involve the legs, though they can affect any superficial vein (e.g. those in the arms). [1]
[3] [4] Medications used to restore a normal heart rhythm (antiarrhythmics) such as ibutilide effectively control atrial flutter about 80% of the time when they are started but atrial flutter recurs at a high rate (70–90% of the time) despite continued use. [1] Atrial flutter can be treated more definitively with a technique known as catheter ...
After a meteoric rise in the music industry, Avicii stepped away from the stage in 2016 to prioritize his mental and physical health. But just two years later, in 2018, the Swedish DJ and musician ...
This is the basis for the so-called fight-or-flight response, but such stimulation can also be induced by stimulants such as ephedrine, amphetamines or cocaine. Certain endocrine disorders such as pheochromocytoma can also cause epinephrine release and can result in tachycardia independent of nervous system stimulation.
In the shorter term, unscheduled time and new, unplanned activities can help alleviate the stress of a packed schedule, while helping us get better at coping when unexpected challenges come up.
