AV nodal reentrant tachycardia. Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical ...
Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans). [1] The normal resting heart rate is 60–90 bpm in an average adult. [2]
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1][2] It can be caused by severe dehydration or blood loss. [3][2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure.
See media help. Arrhythmias, also known as cardiac arrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. [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 ...
Frequency. ~3% [ 6 ][ 7 ][ 8 ] Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [ 2 ] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia, which start within the lower chambers of the heart. [ 2 ]
Another common HCM complication is heart failure, a broad term that means your heart isn’t able to pump enough blood out into your circulation to properly oxygenate the rest of your body. The ...
The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. [3] Tachycardia is a high heart rate, defined as above 100 bpm at rest. [4] Bradycardia is a low heart rate, defined as below 60 bpm at rest.
