Acute myocardial infarction and left bundle branch block with changing axis deviation

Revelation of changing axis deviation at the end of atrial fibrillation without acute myocardial infarction

“…Changing axis deviation has been reported [1][2][3][4][5][6] also during atrial fibrillation [7][8][9] or atrial flutter [10,11].Changing axis deviation has been also reported during acute myocardial infarction [12][13][14][15][16][17][18][19][20][21][22][23] associated with atrial fibrillation too [24,25] or at the end of atrial fibrillation [26] ,also during acute myocardial infarction [27,28]. We present a case of revelation of changing axis deviation at the end of atrial fibrillation without acute myocardial infarction in a 74-year-old Italian man.…”

Left bundle branch block and changing axis deviation during acute myocardial infarction

“…Changing axis deviation has been also reported during acute myocardial infarction [12][13][14][15][16][17][18][19][20][21][22][23] associated with atrial fibrillation too [24,25] or at the end of atrial fibrillation [26,27], also during acute myocardial infarction [28,29]. Left bundle branch block is usually associated with normal or left axis deviation [30].…”

“…Left bundle branch block is usually associated with normal or left axis deviation [30]. Rarely the ECG shows a left bundle branch block with changing QRS morphology [4] and changing axis deviation [7,23,24,30]. There are several possible explanations for the intermittent shift in the QRS axis in the presence of complete left bundle branch block.…”

“…Changing axis deviation has also been reported during acute myocardial infarction [13][14][15][16][17][18][19][20][21][22][23][24] associated with atrial fibrillation [25,26] or at the end of atrial fibrillation [27,28], and also during acute myocardial infarction [29,30]. A left bundle branch block is usually associated with normal or left axis deviation [31].…”
