Hello. Help or assist, please. A problem in the following: mittel (to the boy of 9 years) periodically at daybreak a little bit podkashlivaet (literally few times will cough also all) - he in other room sleeps, therefore I cannot tell or say for certain, every day it occurs or happens or not. I gde-read that, that night tussis at a dog - a sign of disease of heart! Whether so it?! In the rest the boy behaves normally: plays, jumps, eats well...

Hello. Really, tussis in the mornings can testify to disease of heart. Other attributes - fast fatigability on walk, a dyspnea or short wind, cyanosis mucous. Diagnostics of intimate or cardiac diseases includes an electrocardiogram and a picture of a thoracal cavity. On a picture estimate or appreciate a figure of heart, position of a trachea, presence or absence of developments of stagnation in lungs and some other parameters.
