Pulseless electrical activity (PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not.Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests.
Tresillo is a Spanish word meaning "triplet"—three equal notes within the same time span normally occupied by two notes. In its formal usage, [further explanation needed] tresillo refers to a subdivision of the beat that does not normally occur within the given structure.
The two "shockable" rhythms are ventricular fibrillation and pulseless ventricular tachycardia, while the two "non-shockable" rhythms are asystole and pulseless electrical activity. [65] Moreover, in the post-resuscitation patient, a 12-lead EKG can help identify some causes of cardiac arrest, such as STEMI which may require specific treatments.
In music of Afro-Cuban origin, tumbao is the basic rhythm played on the bass. In North America, the basic conga drum pattern used in popular music is also called tumbao [ citation needed ] . In the contemporary form of Cuban popular dance music known as timba , piano guajeos are known as tumbaos .
The intermediate phase focuses on bringing regularity to social rhythms and intervening in the interpersonal problem area of interest. Social Rhythm Metric is heavily used to assess amount of activity being engaged in and the impact of activity on mood. The regularity (or irregularity) of activities is examined, and the patient and therapist ...
Within the group of people presenting with cardiac arrest, the specific cardiac rhythm can significantly impact survival rates. Compared to people presenting with a non-shockable rhythm (such as asystole or PEA), people with a shockable rhythm (such as VF or pulseless ventricular tachycardia) have improved survival rates, ranging between 21 and ...
Overview, including some physiological parameters, of the human circadian rhythm ("biological clock").. Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. [1]
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.
