ECG Pictures Latest 2023 Graded A • Normal rhythm • HR = 300/4.4 = 68 bpm • P wave = sinus origin • QRS complex = preceded by P wave, normal • Normal sinus rhythm • Tall QRS complex, narrow, preceded by P wave • HR = <60 bpm (bradycardia) • P wave = sinus origin • Sinus bradycardia • Irregular rhythm (slow --> speeds up --> slows down) • HR = 70 bpm • PR interval = normal • Respiratory sinus arrhythmia • 2 sinus pauses (arrests) • P wave = sinus node ori...

Automaticity correct answer: Ability to initiate an impulse at a regular interval; "pacemaker" Excitability correct answer: Ability of the heart to respond to a stimulus Conductivity correct answer: Ability of the heart to transmit an electrical impulse from one cell membrane to another Contractility correct answer: The ability of the heart muscle cells to shorten in response to an electrical stimulus Refractoriness correct answer: "Resistant to"; cannot respond to a stimulu...
