Study on the significant symptomatic and effect of treatment methods on 50 patients with 3 degree heart block (23 females and 27 males), were treated at Cardiovascular Hospital during 2002-2003. The results: 70% of total patients had Adams-stokes cyncope. 28% of them were made extent or temporary pacemaker with indications as slow heart rate making a severe Adams-stokes syncope or nearly making Adams-stokes syncope, A-V disorders, young patients with suspective inflammatory induced A-V block. All of patients were treated by Atropine, Theophylin, Ephedrin or Isoprenalin, but only 2 cases decreased of A-V block. 38 patients had successful with permanent pacemaker implantation

To study the significant symptoms and effect of treatment methods on complete heart block. Methods and results: 50 patients (23 female and 27 male) with complete A-V block were studied. 70% of total patients had Adams-stokes syncope. 28% of them were dazzled, dizzied, chest-pain... only one case was without symptom. Average heart rate was 39 beat per minute. 7 patients (14%) had heart failure. All of patients were treated by Atropine, Theophyline, Ephedrine or Isoprenalin, but only 2 cases decreased of A-V block. 38 patients had successful with permanent pacemaker implantation (PPI)

32 patients were studied on model pacemakers implantation as DDD, DDDR pacing, VVIR pacing and AICD (Automatic Implantable Cardioverter defibrillator), in which 23 cases (71.8%) with complete A-V block, 8 cases (25.0%) with Sick Sinus Syndrome and 1 (3.2%) case with Ventricular tachycardia. The implantation technique for all these patients were successfull: VVIR 24 cases (75.0%), DDD + VDD 4 cases (12.5%), DDDR 3 cases (9.4%) and ACID 1 case (3.2%). After implantation, there were 30/32 cases (93.8%) have controled on follow-up, in which 29/32 pacemaker (90.6%) were programed. Not any patients was died. This success improved quality of life for patients in Vietnam whose were suffer from serious arrhythmia heart diseases

By Doppler ultrasound method, 90 healthy persons aged 30-80 were studied. How velocity rate and its values were divided according to time decreased with the age, there was a statistically significant difference between 30-59 age group subjects and >/= 60 age group. Transmitral flow velocity increased progressively with the age, and there was no significant difference in these parameters of transtricuspid flow. The ration of PE/PA, Ei/EA decreased progressively with the age. TRIV, TDE time intervals had the trend to prolonge in > 60 age subjects, whereas TAE seemed to shorten and this difference had statistical significance in comparing to under 60 age subjects
