Abstract
Objective To understand relationship between acute myocardial infarction mith paroxysmal atrial fibrilation and P wave dispersion(Pd) and Maximum P wave interval( Pmax). Methods Acute myocardial infarction with paroxysmal infaction control group were observed Pmax and Pd. Results Pax (123.99±3.61 ms,110. 37±2.58 ms)and Pd (45.82 ±2. 93 ms,29.13 ±3.57 ms)had significant difference between acute myogroup, with a higher sensitivity (92% and 96% ) and specifcity (91% and 95 % ). Conclusion A prolonged Pmax and a increased Pd may be predictive risk of acute myocardial infarction with paroxysmal atrial fibrillation. Key words: Acute myocardial infarction; Paroxysmal atrial fibrilation; P wave dispersion
