<prompt> Answer this question truthfullyWhat is the relationship between wild-type and senile amyloidosis on an electrocardiogram?  <response>: <reason> EKG findings encountered during the evaluation of a patient with wild-type senile amyloidosis include pseudoinfarct pattern, poor R wave progression, atrial fibrillation, first degree AV block, and nonspecific ST-T wave abnormalities. Voltage-to-mass ratio, calculated by the sum of S wave in lead V1 plus R wave in lead V5 or V6 SV1 RV5 or V6 divided by the echocardiographic muscle cross-sectional area, has been implicated to have high sensitivity and specificity for wild-type senile amyloidosis.
