△ Analyze the 12-lead ECG of a 55-year-old male patient to determine heart rate, intervals, axis, rhythm, and any abnormalities. ○ Determine heart rate ☼ The heart rate is 62 beats per minute, calculated from the ECG. ○ Measure PR interval ☼ The PR interval is 114 ms, as observed on the ECG. ○ Measure QRS duration ☼ The QRS duration is 90 ms, as observed on the ECG. ○ Measure QT interval ☼ The QT interval is 422 ms, as observed on the ECG. ○ Determine QRS axis ☼ The QRS axis is 79 degrees, indicating a normal axis. ○ Assess rhythm and abnormalities ☼ The rhythm is normal sinus rhythm. There is no evidence of ischemia, infarction, or other abnormalities. ○ Provide recommendation ☼ A stress ECG is recommended due to the patient's known history of heart condition. ✧ Heart rate: 62 bpm; PR interval: 114 ms; QRS duration: 90 ms; QT interval: 422 ms; QRS axis: 79 degrees; Rhythm: Normal sinus rhythm; Other findings: None; Recommendation: Stress ECG. ☺ Heart rate: 62 bpm PR interval: 114 ms QRS duration: 90 ms QT interval: 422 ms QRS axis: 79 degrees Rhythm: Normal sinus rhythm Other findings: None Recommendation: Stress ECG
