sinus bradycardia and inferior ischemia

a recent ekg my husband had says  it is abnormal because of sinus bradycardia and T wave abnormality- consider inferior ischemia what does this mean ? he has had bypass in 2000 and takes metropolol


This discussion is related to Inferior ischemia.

Bradycarda is a heart rate less than 60 bpm at rest. That would be designated by the per minute count of the  "P" wave on the EKG.  May or may not be significant.  The danger is a very slow heart rate and that can cause blood clots, 50-60 isn't a problem.

It hasn't been stated the configuration of the T wave abnormality.  It can be a tall T wave and the cause includes hyperkalaemia (too much potassium in the blood), hyperacute myocardial infarction (heart attack...heart muscle damage) and left bundle branch block (causes arrhythmia).  Usually requires other abnormal wave forms in addition to the t wave abnormality.

Causes of small, flattened or inverted T waves are numerous and include ISCHEMIA (blocked or partially blocked arteries), age, race, hyperventilation, anxiety, drinking iced water, LVH, drugs (e.g. digoxin), pericarditis, PE, intraventricular conduction delay (e.g. RBBB)and electrolyte disturbance.

Abnormal T waves has many causes and your post indicates ischemia as the cause. Any EKG test requires other evidence to make a diagnosis.
