The request 3
A 51 year old male applies for $1,000,000 of life insurance.
There is a history of some generalized fatigue, palpitations, and one recent episode of syncope occurring after exercise which was initially felt to be aggravated by dehydration.
One older brother died suddenly a few years back but no specific cause was identified. There has been an echo done recently but the results are not available at the moment.
Luckily you do have an ECG to interpret (are you surprised? I think not! This is, of course, an ECG of the week series!!!)
The ECG 4
Here is the ECG!! How would you interpret this tracing?
The interpretation 5
ANSWER:NSR with rate ~72 bpmPR/QRS/QT intervals appear WNL. • PR ~ 0.16
sec• QRS ~ 0.08
sec• QTc ~ 0.42
secAxis: LAD ~-30o
Hypertrophy: NoneQ waves: Lead III, ? Small r waves in aVFST-T wave changes: ST segment depression noted in leads I, aVL as well as V4-6 with inverted T waves in I, aVL, V2-6
The echo report is obtained and documents the diagnosis of hypertrophic cardiomyopathy.
Hypertrophic Cardiomyopathy—ECG findings 6
A normal ECG is
uncommon! It is seen in
<10% of those with
HCM!!!
Frequently there are
prominent voltages and
repolarization changes
Hypertrophic Cardiomyopathy
Facts to know
However, the ECG changes of HCM are not specific to HCM.
An echocardiogram is frequently needed to help
establish the diagnosis
Q waves, especially in
the inferior and lateral
leads are commonly
seen. This reflects
depolarization of the
hypertrophied septum.
Deeply inverted T waves are
frequently seen—especially in
V2-4.
Left axis deviation is common.
Bi-atrial enlargement is
common
