“…Situations related to increased duration (and a tendency for atrial fibrillation) include hypertrophic cardiomyopathy [6], status post cardiac surgery [43], cardiac infarction and failure [15,39], increased left-atrial size and pressure [3], ischemic heart disease and exercise [29,35], as well as hypertensive and valvular heart disease, pericarditis, and dilated cardiomyopathy [8,42]. Coronary reperfusion following angioplasty can reshorten the P-wave and thus protect against atrial fibrillation [2]. In the light of the above, we should explain the possible rationale for any shortening or prolongation of atrial conduction time during laparoscopic operations, as expressed in the mean and maximal duration of the P-wave.…”

Primarily, a decreased P-wave duration was expected, due to cardiac autonomic sympathetic predominance during PP. Its prolongation during PP may reflect some cardiac pathophysiological (structural and functional) changes, including influence on cardiac ion channels during depolarization. Usually, clinical consequences related to laparoscopic cholecystectomy are absent, but clinical awareness should be maintained for cardiac diseased patients undergoing prolonged laparoscopic procedures.

Atrial fibrillation (AF) is a major arrhythmia with a high prevalence among population. AF is not uncommon in the setting of coronary artery disease, including myocardial infarction (MI) and acute coronary syndromes (ACS). Percutaneous coronary interventions (PCI) have significantly improved outcomes of patients with acute MI and acute coronary syndromes. Nevertheless, the AF was reported to occur in patients with MI and ACS undergoing PCI. New onset AF after PCI for MI and ACS, though being infrequent, was associated with worse clinical course and prognosis. The predictive value of AF has tendency to change in parallel with improvements of reperfusion strategies and comprehensive treatment. Observational studies suggest better patency of culprit vessels achieved by PCI was accompanied by improvement in signal-averaged electrocardiography indices of atrial electrophysiological properties and higher rate of restoration of sinus rhythm during primary PCI as compared with thrombolysis. The adequate management of arrhythmia is required to reduce the risk of complications.

Atrial fibrillation (AF) may occur during or after percutaneous coronary interventions (PCI). The purpose of the study was to determine the clinical, angiographic and electrophysiological predictors of AF after PCI. 225 patients undergoing PCI (mean age of 65 ± 11 years) who had sinus rhythm (SR) before balloon inflation were taken to study. Of these 22 developed AF in catheterization laboratory after balloon inflation or in 24 h following PCI (AF group), 203 did not (SR group). The patients in AF group were older (67 ± 9 vs. 63 ± 8 years, p < 0.05) and their ventricular ejection fraction was lower than SR group (56 ± 5 vs. 45 ± 7%, p < 0.05). The P-wave dispersion was significantly higher in AF group than SR group (53 ± 8 vs. 29 ± 10 ms, p < 0.001). For the patients with ST elevation myocardial infarction, the time from the onset of symptoms to balloon inflation was 3.7 ± 1.7 h in SR group. It was longer in AF group (4.1 ± 1.8 h, p < 0.05). TIMI perfusion grades 2 and 3 were achieved in 23 of 27 patients in SR group, and 5 of 8 patients in AF group. Multivessel disease was documented in 93 of the patients in SR group, and 12 in AF group. Clinical reperfusion was thought to be established in 20 in SR group, and 4 in AF group. In conclusion, our results show the importance of clinical factors, angiographic results and P-wave analysis in prediction of AF following PCI.
