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.
Ashman phenomenon, also known as Ashman beats, describes a particular type of wide QRS complex that is typically, but not always seen in atrial fibrillation.It is a type of cardiac aberrancy and it is more often misinterpreted as a premature ventricular complex.
Ventricular tachycardia (VT or V-tach) is a potentially life-threatening cardiac arrhythmia that originates in the ventricles. It is usually a regular, wide complex tachycardia with a rate between 120 and 250 beats per minute.
Focal V-tach is where a specific area of the ventricle has abnormal automaticity. The automaticity rate is the frequency at which a cell sends out a signal, so for the pacemaker cells in the SA node the rate is between about 60 and 100 signals per minute, resulting in 60 to 100 beats per minute, let’s just say 60 beats per minute, so one beat ...
Cardiac aberrancy is a type of disruption in the shape of the electrocardiogram signal, representing abnormal activation of the ventricular heart muscle via the electrical conduction system of the heart. Normal activation utilizes the bundle of His and Purkinje fibers to produce a narrow (QRS) electrical signal.
A Delaware woman who was reported missing last week after she didn't show up to work for several days was found dismembered in a car over the weekend, police said.
Precordial thump is a medical procedure used in the treatment of ventricular fibrillation or pulseless ventricular tachycardia under certain conditions. The procedure has a very low success rate, but may be used in those with witnessed, monitored onset of one of the "shockable" cardiac rhythms if a defibrillator is not immediately available.
"That membrane protects [the egg] from bacteria," she said. "You can just crack the egg into a small bowl, cover it with plastic wrap or a lid, and use it within two days – making sure you cook ...
