ECG is an electrocardiogram. This test is where wires are attached to the
chest to measure the electrical activity of the heart relative to time.
Sinus rhythm means that the initiation of the electrical signal is coming
from the sinus which is the natural pacemaker of the heart (normal).
80/minute is the heart rate (normal is 60-99). Intermediate axis means the
direction of the electrical vector representing the ventricular contraction
(the squeezing by the lower heart chambers) is neither abnormally leftward
or rightward. RBBB is Right Bundle Branch Block which describes the loss
of electrical signals coming down the Right Bundle. Electrical signals are
transmitted from the atria (upper heart chambers) to the ventricles through
both Left and Right Bundles in a normal heart. Non-specific ST and T wave
changes are sensitive for picking up recent or ongoing ischemia. Though
sensitive, this is not a specific finding by itself but with RBBB, one has
to worry about occlusive coronary disease especially if the rest of the
history and physical exam suggests it.
