Cardiac diseases are a major health concern and many of the patients in a general practitioner’s (GPs) office have heart conditions. Hand-held ultrasound device (HUD) can improve the GP’s diagnostic possibilities. We want to evaluate if a training program with focus on practical ultrasound skills can help the GP’s to correctly diagnose certain heart conditions by using HUD. If successful, unnecessary referrals could be avoided and patients in need of specialist care would avoid delay in diagnosis and treatment.
