Atrial fibrillation is a common arrhythmia occurring in about 10-20% of patients with acute myocardial infarction. P-wave dispersion and P-wave duration have been used to evaluate the discontinuous propagation of sinus impulse and the prolongation of atrial conduction time respectively. This study was conducted to compare the effects of reperfusion either by thrombolytic therapy or primary angioplasty on P wave duration and dispersion in patients with acute anterior wall myocardial infarction. We have retrospectively evaluated 72 consecutive patients (24 women, 48 men; aged 58 ±12 years) experiencing a first acute anterior wall myocardial infarction (AMI). Patients were grouped according to the reperfusion therapy received (primary angioplasty (PTCA) versus thrombolytic therapy). Left atrial diameter and left ventricular ejection fraction (LVEF) were determined by echocardiography in all patients. Electrocardiography was recorded from all patients on admission and on pach day of hospitalization. Maximum (P max) and minimum (P min) P wave durations and P wave dispersions (PWd) were calculated before and after treatment. There were no significant differences between the groups regarding age, gender, left ventricular ejection fraction (LVEF), left atrial diameter and volume, cardiovascular risk factors and duration from symptom onset to treatment. PWd and P wave durations were significantly reduced after PTCA (mean P max was 113±11 ms before and 95±17ms after the treatment [p=0.007]. Mean PWd was 46±12 ms before and 29±10 ms after the treatment (p=0.001). Also, P max and PWd were significantly lower in PTCA group (for P max 97±22 ms versus 114±16 ms and for PWd 31±13 ms versus 55±5 ms, respectively). Primary angioplasty reduces P max and P wave dispersion. (Türk Kardiyol Dern Arş 2004; 32: 302-308)
