There are many false positives associated with an EKG and requires further testing to validate. RBBB, if valid, indicates some blockage of electrical pathways for transmitted impulses to contract the heart chambers. If there is blockage, it may cause irregular heartbeats...very common to have extra and/or delayed heartbeats.
T wave abnormality, if valid, indicates there is some blockage of coronary arteries causing ischemia (lack of blood flow) in the location shown.
Do you know if the test come back abnormal because the Pacemaker takes over? I don't know if this is normal or if I should be concerned. The 1st abnormal ECG was the afternoon after the surgery. The 2nd abnormal ECG was the following day.
The abnormal EKG can be related to a loss of atrial-ventricular synchrony in patients with a pacemaker. Or abnormal EKG can be due to an artefact (equipment problem), etc. If there seems to be a problem with ischemia, a stress test would be appropriate as an EKG is not very relaible for that dx..
Mini stroke (TIA) represents temporary stroke warning symptoms. A stroke can be impairment of sensation, level of consciousness, balance, or voluntary motion caused by a rupture or obstruction of an artery in the brain. In short: a stroke is a brain attack. TIA is not a full-blown stroke, but mimics one as you suggest.
An Electrocardiogram (EKG) to confirm a regular heart rate, blockage of electrical impulses through the heart, etc. It will not show any blood flow through the vessels, bleeding, blockage, etc..The ekg only analyzes electrical wave impulses.
A computerized tomography (CT scan) of the brain to look for bleeding would be appropriate test. Or Carotid ultrasound to look for narrowing of the large blood vessels in the neck.
