Myocardial ischemia occurs when there is a relative lack of O2 supply to the myocardium and metabolite removal from the heart for a given O2 consumption; it is classically noted as symmetrical __ wave changes.
ECG changes are an early indicator of myocardial ischemia.
The majority of ischemia occurs intraoperatively.
When examining an EKG for a suspected posterior MI, you would look for ST ______ in leads V1 and V2.
When identifying ischemia in the absence of LVH or LBBB, new ST elevation, or ST depression with T-wave changes must be identified in how many contiguous leads?
An infarction of which of the following areas would most likely have the greatest effect on SA/AV node conduction?
L BBB and LVH make the diagnosis of MI impossible (or rather difficult).
