What kind of medication would you recommend to help a person with heart irregularity? A person I am talking about has a problem of irregular heart beating. The pulse is quite strong, but there is a strong uneveness of the time between the beats (because of which the heart stabilizer was installed and used). After its installation the pulse became less strong and quite even, but the strenghth of pulse became a little uneven. My question is: what kind of medication, if any would you recommend to improve functioning of the heart? Thanks very much in advance! There were conduction problems, which were leading to irregularities I mentioned above. This person had emotional shocks in the past, which had caused heart abnormalities. This person suspectedly had several heart attacks, one of which led to a clinical death. When this happened, this person was reanimated (10 minutes after the heart stopped). When I talk about improving functioning of the heart , I mean optimization of its work so that person feels good. The installed pacemaker is an atrioventricular one. The person suffers from the pace slowering.

My doughter aged 4 years with weight 17 kg. has ASD heart defect, here ecocardiogram Interpretation is - Fossa ovalis ASD(16x17cm), left to right shunt. Adequate rims. Mild TR. TR max PG=38mmHg. Mildly doming pulmonary valve. RVOT max PG=28 mmHg. Dilated RA and RV. RVIDd=2.6 cm, Normal ventricular function. Normal arch. Doctor advice for ASD device closure but we worried about it don`t know result or any side effect after device fixing so kindly advice if this ASD size can be recover naturally with age growth or its compulsory to go for ASD closer device. I`m writing this email with a hope to get complete advice.

We are looking into adopting a little boy from China. His "issue" is Congenital incomplete brain development. His CT scan states:
Indicated in CT image:
Flake-like low density shadow was observed in right side ventricle with clear borders, obviously
widened surrounding cerebral sulcus, obviously widened right side ventricle; midline was right
shifted.

Imaging:
1. Right side ventricle encephalomalacia lesion
2. Maldevelopment of right brain

Thoughts?
