Which statement is correct regarding premature ventricular complexes (PVCs)? PVCs originate from the atrium. PVCs may be unifocal or multifocal in origin. PVCs will not lead to ventricular tachycardia. PVCs only originate from one site in the ventricles. - PVCs may be unifocal or multifocal in origin. A regular rhythm at a rate of 40-60 beats per minute, with narrow QRS complexes, and no visible P waves, is consistent with the presence of: atrial fibrillation. sinus bradycardia. juncti...

NPTE study guide 2023 Most common thumb deformity in patients with RA - ANS-Boutonniere deformity - metacarpophalangeal joint flexion with interphalangeal hyperextension. Chronic synovitis associated with RA eventually forces MCP into forced flexion, placing tension on the IP extensor mechanism, resulting in hyperextension. Maximum amt of knee flexion required to for gait - ANS-0-60 degrees, the greated amount being from initial to midswing. Transtibial amputation changes in stance and ...
