5-Lead ECG (Continuous Monitoring): - Answer-Right arm
(RA):** White electrode below the right clavicle.
Left arm (LA):** Black electrode below the left clavicle.
Left leg (LL):** Red electrode on the left side of the
abdomen.
Right leg (RL):** Green electrode on the right side of the
abdomen.
Precordial (V1):** Brown electrode placed at the fourth
intercostal space, just to the right of the sternum.
Mnemonic:** "White on right, smoke (black) over fire (red),
green goes to the ground (right leg), brown is central."
What is cardiac stress test? - Answer-the patient walks or

Proper electrode placement is essential to avoid artifacts
and ensure accurate readings
Precordial (Chest) Leads (V1-V6):**
V1 Fourth intercostal space to the right of the sternum.
v2Fourth intercostal space to the left of the sternum
v3Midway between V2 and V4.
V4 Fifth intercostal space at the midclavicular line.
V5At the anterior axillary line, horizontal to V4.
V6 At the midaxillary line, horizontal to V4 and V5.
What is pharmacological stress test - Answer-Patients who
are cognitively impaired and unable to follow directions or
physically disabled or deconditioned will not be able to
achieve their target heart rate by exercising on a treadmill
or bicycle.
must avoid xanthine derivatives (theophylline,
aminophylline, caffeine) for 24-48hrs prior (they block the
effects of the vasodilating agents.)
