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)

The electrocardiographic analysis of heart blocks provides great opportunities for the discussion of mechanisms of electrical cardiac conduction, serving as “teachable moments” in medicine. Recognition of heart blocks can sometimes be a challenge as they can present in many forms, different severities and levels of blocks that present as varied patterns on electrocardiographic tracing. The ultimate key to correct diagnosis rests on adequate understanding of normal electrophysiology of the electrical system of the heart. While it is vital to recognize the pattern, we should always know and understand the physiology behind the pattern. This article presents a detailed analysis of a case of heart block which can easily be misinterpreted on first look. The case is featured not for its rarity but for the interesting concepts in cardiac electrophysiology that are highlighted. Navigation of the different elements of tracing can be an adventure and a great learning experience enjoyed by both students and experts.

Arrythmias are often present and may lead to unexpected death in acute myocarditis. Occasionally, conduction disturbances are seen with varying degree of heart block yet complete atriove ntricular block is rare. We experienced a case of transient complete heart block caused by coxsackie B5myocarditis in a previously healthy 12-year-old girl. During the use of a transvenous temporary pacemaker for 5 days, the abnormal cardiac rhythm changed to sinus rhythm and clinical status improved progressively.

Torsades de pointes (TdP) is a rare complication of a complete atrioventricular block with QT prolongation. Additional risk factors, such as hypokalemia, may increase the risk of TdP during atrioventricular (AV) block. We experienced a case of TdP, caused by a complete heart block and hypokalemia, which was successfully treated by implanting a permanent pacemaker and correction of the electrolyte imbalance.

The electrocardiograms of a total of 12,796 patients taken in the past three years at Severance Hospital were reviewed for conduction disturbances which were found in 314 cases(2.46%). Th first degree atrioventricular block occurred in 65 cases, and second degree atrioventricular block with Wenckebach periodicity in 13. There were 9 cases of third degree atrioventricular block with nomal QRS complexes causing Adams-Stokes attacks which represented 2.9% of all conduction disturbances. It occurred equally in both sexes and predominantly after 6th decade of life. There were 99 cases of complete right bundle branch block(RBBB) and 12 cases of complete left bundle branch block(LBBB). The latter were mainly associated with significant heart diseases. As for the intraventricular conduction defects other than the simple bundle branch blocks, the findings were as follows; 1. Simple hemiblocks were found in 92 cases or 0.73% of total series and 29.3% of all conduction disturbances. Left anterior hemiblock(LAH) occurred 3 times more frequently than left posterior hemiblock(LPH). 2. Partial bilateral bundle branch block(BBBB) were found in 25 cases representing 0.2% of the total series and 8.0% of all conduction disturbances. Among the 25 cases of BBB, 11 had RBBB plus LAH, 10 RBBB plus LPH, 1 LBBB plus first degree A-V block, and 3 LBBB of diphtheritic cardic involvement. Trifascicular heart block causing Adams-Stokes attacks occurred in 9 of the 25 cases resulting in death in 7 cases. The underlying diseases were ischemic heart disease, hypertensive heart disease, congenital heart disease and diphtheritic carditis. This report represents the first electrocardiographical documentation of occurrence of trifascicular heart block progressing from BBBB in Korea.
