Low accuracy from high variability limits PCP pocket ultrasound for LVH detection; leaves open utility after refined training and validation.
Does measurement of left ventricular mass index by primary care physicians using a pocket ultrasound device provide accurate results compared to standard echocardiography in patients with hypertension?
While primary care physicians can feasibly use pocket ultrasound to measure left ventricular mass, a brief 4-hour training session yields high variability and insufficient diagnostic accuracy for routine clinical use without further training and feedback.
