Question

Various terms may be used to describe an irregular rhythm, which may be ________, ________, or ________. A ______ rhythm is one in which the R-R intervals are not the same, the shortest and longest R-R intervals vary by more than 0.04 sec, and there is a repeating pattern of irregularity. A ______ rhythm may be due to grouped beating (a repeating pattern of irregularity). This rhythm may also be called a grossly or totally irregular rhythm?

1) Sinus
2) Normal
3) Ventricular
4) Regular
5) Regular

Answer 1

The terms used to describe an irregular rhythm of the heart include sinus, ventricular, or bradyarrhythmias. A 'regular irregular' rhythm includes varied R-R intervals with a repeating pattern, while an 'irregularly irregular' rhythm may involve grouped beating. Sinus rhythm is the normal rhythmic beating established by the heart's pacemaker cells.

Step-by-step explanation:

Various terms may be used to describe an irregular rhythm, which may be sinus, ventricular, or bradyarrhythmias. A regular irregular rhythm is one in which the R-R intervals are not the same, the shortest and longest R-R intervals vary by more than 0.04 sec, and there is a repeating pattern of irregularity. A irregularly irregular rhythm may be due to grouped beating (a repeating pattern of irregularity).

The normal, rhythmic beating of the heart is called sinus rhythm. It is established by the heart's pacemaker cells in the sinoatrial node. However, in cases of arrhythmias, this rhythm gets disrupted leading to irregularities.

Cardiac arrhythmias are abnormal heart rhythms, which can be potentially life-threatening and often can be interrupted with a cardiac defibrillator, which delivers an electrical shock to the heart, effectively "rebooting" it.
