From: Hand-held echocardiography: added value in clinical cardiological assessment
Conclusiveness of echocardiographic examination according to referral question: the diagnostic accuracy of the HHD seems to be affected by the type of referral question. HHD showed a good reliability in the examination of patients referred for arterial hypertension or palpitations, but was less accurate for those who presented dyspnoea or chest pain, as a result of biases in the measurements of wall thicknesses, and in the assessment of valvular diseases and regional wall motion.
