Status Asthmaticus
Report:
Sinus tachycardia
Right axis deviation +120o
Clockwise rotation
Comment:
Right axis deviation may still be a normal variant in a young subject; in this case we can be sure it was a result of cor pulmonale as the axis normalised with clinical improvement ( Fig 210a below).
The tachycardia produces a spurious ST segment depression also seen in Fig 209a: an almost perfect arc with PR segment in lead 2.
This patient did not take time to become cyanosed or bradycardic â she stopped breathing rather suddenly.
210a. 211. 46 year old lady with COAD and atypical chest pains. The consultant reported: âNo changes. Old inferior MI. Exclude PEâ
