“…These data confirm the apparent 'paradox' of the reported lower frequency of atrial fibrillation among Asians [43] and black Africans [44] than among whites. As all ethnic groups had similar access to healthcare in the setting of the present study, our findings do not support the hypothesis that under-ascertainment of atrial fibrillation because of poorer access to medical care in nonwhite ethnic groups may be responsible for the ethnic discrepancy.…”

“…Incidence of atrial fibrillation very well correlates with study done by Novaro GM et al 16 His study showed incidence of 4.7% in Asians. AF is associated with an increased in hospital mortality probably because it is associated with large infarcts and is seen more commonly in patients with cardiac failure, complex ventricular arrhythmias, advanced AV block, atrial infarction and pericarditis, as incidents increases with age.…”

Background: Arrhythmias are a common occurrence in ACS. This study was undertaken to analyze the incidence, frequency and type of arrhythmias in relation to the site of infarction to aid in timely intervention to modify the outcome in MI and to study the significance of Reperfusion arrhythmias.Methods: 100 patients were evaluated. ECG and cardiac enzymes were studied. Arrhythmias complicating AMI in terms of their incidence, timing, severity, type, relation, reperfusion and results were studied.Results: Of the 100 cases, 74% were males and 26% females of which incidence being common between 4th to 7th decades of life. AMI was common in patients with Diabetes and Hypertension (23% each). Incidence of AWMI (58%) is higher than IWMI (40%). Out of all arrhythmias, Ventricular Tachycardia was seen in 24% cases with 50% mortality and preponderance to Antero Lateral Myocardial Infarction. Sinus Tachycardia was seen in 23% of cases with preponderance to Antero Lateral Myocardial Infarction and persistence of Sinus Tachycardia was a prognostic sign, mortality being 22%. Complete Heart Block and Sinus Bradycardia were seen with IWMI, incidence being 53.8% and 100% respectively. Bundle Branch Block was common in AWMI (31%) than IWMI (10%). Among 64 thrombo-lysed cases, 21 had Reperfusion Arrhythmias without any mortality, whereas remaining 43 without Reperfusion Arrhythmias had mortality of 18.6%.Conclusions: According to the study, Tachy-arrhythmias are common with Anterior Wall Myocardial Infarction and Brady-arrhythmias in Inferior Wall Myocardial Infarction. Reperfusion Arrhythmias are a benign phenomenon and good indicator of successful reperfusion.

“…Studies reporting a reduced risk of AF among non-white races have been limited by the use of a single non-white comparator group, [4][5][6][13][14][15][16] absence of incident event data, [3][4][5][16][17][18][19] failure to adjust for comorbidities, 3,17,18 or enrollment of select populations (including patients with acute decompensated heart failure, 4 with acute myocardial infarction, 14 on hemodialysis, 20 and after coronary artery bypass graft surgery). 21 Our results provide a more comprehensive assessment of the risk of AF among a diverse population of patients seeking care at California hospitals without limitation to a specific disease condition.…”
