Anxiety can profoundly alter the ECG, probably via changes in autonomic nervous system function, as evidenced by the ECG normalizing with manoeuvres that normalize autonomic function (reassurance, rest, and anxiolytics and beta-blockers), with catecholamine infusion producing similar ECG changes. Left bundle branch block is a condition in which theres a slowing along the electrical pathway to your hearts left ventricle.

Left axis deviation of at least -45 degrees; Lead aVL is qR pattern; Sharp R waves and deep S waves on leads II, III, and aVF; QRS widens no more than 0.02 s in pure LAFB, but the presence of myocardial infarction or left ventricular enlargement may produce a more substantial QRS widening; Deeper S waves on precordial leads 7. abnormal ecg
