Rate: 100-250 bpm · Regular or slightly irregular

Rate: Indeterminate — no organized rhythm · Chaotic, no pattern

Rate: None (flatline) · None

Rate: Variable — any rate, no pulse · Variable — may appear organized

Rate: 60-100 bpm (usually normal) · Regular

Rate: Atrial > Ventricular · Irregular — grouped beating pattern

Rate: Atrial > Ventricular · Regular atrial, irregular ventricular

Rate: Atrial: 60-100. Ventricular: 20-60 (junctional or ventricular escape) · Regular P-P, Regular R-R, but NO relationship between them

Rate: Underlying rate + ectopic beats · Irregular due to ectopic beats

Rate: 150-300 bpm · Irregular — characteristic "twisting of the points"
