Some observations on abnormal rhythms: Part 3

on 7.7.05 with 0 comments



Paroxysmal atrial rhythm (tachycardia, paroxysmal or flutter fibrillation ) in a young person without obvious evidence of cardiac disease rises the possibility of :

1-Thyrotoxicosis.
2-WPW syndrome.
3-Lone atrial fibrillation .

TALL symmetrical T waves in the precordial leads might be due to :

1-acute subendocardial ischemia , injury or infarction.
2-recovering inferior wall myocardial infarction.
3-hyperacute phase of anterior wall myocardial infarction.
4-Prinzmetal 's angina.
5-true posterior wall myocardial infarctions.
6-hyperkalemia.

Generalized LOW voltage might be due to :

1-incorrect standardization.
2-emphysema.
3-marked obesity or thick chest wall.
4-pericardial effusion.
5-myxedema.
6-hypopituitarism.
7-Cardiac Amyloid.
8-Severe cardiomyopathy
9-Global Myocardial iscehmia.


Acute rheumatic frequently associated with:

1-sinus tachycardia.
2-non paroxysmal AV nodal tachycardia( idionodal tachycardia).
3-prolonged PR interval.
4-2nd degree AV block .
5-prolonged QT interval.

NB: it is NEVER associated with 3rd degree AV block
