Which statement is correct regarding premature ventricular complexes (PVCs)?
PVCs originate from the atrium.
PVCs may be unifocal or multifocal in origin.
PVCs will not lead to ventricular tachycardia.
PVCs only originate from one site in the ventricles. - Correct Answer- PVCs may
be unifocal or multifocal in origin.
A regular rhythm at a rate of 40-60 beats per minute, with narrow QRS complexes,

is greater than or equal to 35 mm in which of the following leads?
V1 or V2 S-wave, II or AVF R-wave
V1 or V2 S-wave, V3 or V4 R-wave
V1 or V2 S-wave, V5 or V6 R-wave
V3 or V4 S-wave, V5 or V6 R-wave - Correct Answer- V1 or V2 S-wave, V5 or
V6 R-wave
,Lead V6 should be placed
left mid-axillary line, 5th intercostal space.
mid-clavicular level on the patient's right side.
fifth intercostal space on the patient's right side.
mid-sternal level in the center of the patient's chest wall. - Correct Answer- left
mid-axillary line, 5th intercostal space.

An exercise stress test performed to:
evaluate disorders such as CHF.
identify ischemic changes due to CAD.
mimic the diastolic heart changes at rest.
determine if a CABG procedure is necessary. - Correct Answer- identify ischemic
changes due to CAD.
, You are beginning the warmup stage of a treadmill stress test and you observe a
3mm ST segment depression in leads I and aVL. What is the first thing you should
do?
continue with your pre-test activities
initiate the first stage of the protocol
stop the treadmill and notify the physician

The intrinsic rate of the Purkinje network in the ventricles is:
20 to 40 beats per minute.
40 to 60 beats per minute.
60 to 100 beats per minute.
100 to 150 beats per minute. - Correct Answer- 20 to 40 beats per minute.
What is the heart rate of an ECG with a constant R-R interval of 30mm recorded at
a standard paper speed? - Correct Answer- 50 bpm
RR duration = R-R interval/paper speed
HR=60s / RR duration
30mm / 25mm/s = 1.2s
60s / 1.2 = 50bpm
