QRS duration: __________ QT duration: ____________
Ventricular rate and rhythm: _____________
Atrial rate rhythm: _____________________
PR interval: __________________________
Interpretation: ________________________
Introduction:
The electrocardiogram or ECG is a tool that is used to record a patient’s heart rate in real time. The heartbeat produces electrical signals that are recorded in this tool. It is recorded in a waveform, which has P, Q, R, S, T, and U components. The ECG is interpreted by doctors to know the condition of patients.
Explanation of Solution
The heart rate of the patient is regular with normal electrical activity of the heart. There was one PAC (premature atrial contractions), also known as atrial premature beats, at sixth position, which occurred naturally. The ECG tracing is interpreted as normal sinus rhythm.
QRS duration: The duration of the QRS complex is less than 0.12 seconds.
QT duration: It is more than 0.12 seconds.
Ventricular rate and rhythm: The ventricular rate is regular and between 60 and 100bpm. Ventricular rhythm is less than 0.12 seconds.
Atrial rate rhythm: It is regular with the heart rate up to 100 bpm and occurrence of one PAC at the 6th complex.
PR interval: Duration is less than 0.20 seconds.
Interpretation: The patient’s heart rate is between 60 and 100 bpm, so the graph represents ECG tracing of Normal Sinus Rhythm (NSR) with one PAC at the sixth complex.
QRS duration: 0.6 seconds QT duration: 0.40 seconds
Ventricular rate and rhythm: 86 bpm
Atrial rate rhythm: 86 bpm
PR interval: 0.16 seconds
Interpretation: The graph shows normal sinus rhythm with 86 bpm having one atrial premature beat at the sixth complex

STATEMENT A B C D Arterial blood pressure is independent of Blood volume Heart rate Blood viscosity Influx of calcium ions Identify the TRUE statement(s). There may be several correct answers. An increased cardiac output is reflected in an elevated diastolic pressure. An increased cardiac output is reflected in a decreased diastolic pressure. An increase in the force of contraction produces an elevated systolic pressure. An increase in the force of ventricular contraction produces decreased diastolic pressure. In the absence of compensations, the stroke volume will decrease when Blood volume increases Venous return increases Contractility increases Arterial blood pressure increasesarrow_forward
