Describe treatment of the above. Case. A 55 year old male calls 911 because his “heart is racing.” He initially is alert, oriented, and has mild shortness of breath. On physical exam, he has a regular tachycardia at 180, and monitor shows a regular, narrow-complex tachycardia. He denies chest pain. Midway through transport, he becomes less responsive, and his blood pressure drops as he starts sweating profusely.. . 1- RHYTHM. : regular . 2-RATE. . : more than 100bpm .. 3- P WAVE. : normal (up right ,rounded ). 4-PR INTERVAL. : normal . 5- QRS COMPLEX. : normal duration . 6-ST SEGMENT. : . isoelectric. tachyarrhythmias. د. حسين محمد جمعة . اختصاصي الامراض الباطنة . البورد العربي . كلية طب الموصل . 2010.
