SUBJECTIVE: Jim is a 55-year-old male who presents to the Urgent Care Clinic after an episode of intense chest pain, tingling and numbness that radiates down his left arm that occurred while driving his daughter to a school concert. The pain was relieved by placing a nitroglycerin tablet under his tongue. Because of concerns from both his daughter and wife, he is here today for a follow-up. OBJECTIVE: BP is 145/90, respirations 20, pulse is regular. Temperature normal. His chest X-ray reveals a pacemaker on the left, cardiomegaly and increased markings of congestive heart failure. The EKG reveals normal rate and rhythm. ASSESSMENT: 1. Angina pectoris 2. Cardiomegaly 3. Possible CHF 4. Hypertension
