: duration between the start of the P deflection and the start of the QRS group QT segment: time from the start of the QRS complex and the conclusion of the T wave
Part B Exercise: Interpreting Electrocardiograms In Part B training, you will be provided with a number of ECG readings and required to read them. This section will assist you build your skills in detecting various cardiac rhythms, arrhythmias, and other ECG irregularities. Question 1: ECG strip displays a ventricular rate of 120 thumps per minute (bpm), with a steady pattern and a P peak before every QRS complex. The PR segment is 0.20 seconds, and the QRS segment is 0.08 moments. Which is the analysis of this ECG tracing? Reply: Sinus tachycardia Reason: Sinus tachycardia is marked by a cardiac rate more than 100 bpm, with a steady rhythm and a P wave before each QRS segment. The PR period and QRS group length are inside normal ranges. Question 2: part b practice interpreting electrocardiograms answer key
P wave: denotes atrial depolarization QRS complex: denotes ventricular depolarization T curve: signifies ventricular repolarization PR period : duration between the start of the P
