atropine/infarction

The degree of A-V block increased after intravenous administration of atropine in 10 nondigitalized patients with acute inferior myocardial infarction who had narrow QRS complexes during periods of 1:1 A-V conduction. Short episodes of 3:1, 4:1 and 5:1 A-V block were seen to emerge: (a) in 6

BACKGROUND Patients with recent myocardial infarction frequently require a myocardial perfusion study for risk stratification. However a conclusive study cannot be accomplished in many due to non-attainment of target heart rate. OBJECTIVE To evaluate the effect of pre-stress administration of

The action of atropine on heart rate, prevention of arrhythmias, electrical activity and heart contractility was studied in 35 patients with acute myocardial infarction. Atropine had a favourable effect in 24 out of 27 patients with sinus bradycardia, and hypotension present in some cases was

The purpose of this study was to investigate the therapeutic response to atropine of patients experiencing hemodynamically compromising bradyarrhythmia related to acute myocardial infarction (AMI) in the prehospital (PH) setting and the therapeutic impact of the PH response to atropine on further

Mechanisms responsible for atrioventricular (AV) block during acute inferior myocardial infarction are only partially understood. Increased parasympathetic tone is the factor usually postulated; however, persistence of AV block after atropine administration is frequently observed. Adenosine, an

Fifty-six patients with acute myocardial infarction complicated by sinus bradycardia (SB) were treated with intravenous atropine and monitored in a coronary care unit. Atropine decreased or completely abolished premature ventricular contractions (PVCs) and/or bouts of accelerated idioventricular

Atropine has also been suggested to potentially worsen the ischemic situation in patients who are in the midst of acute coronary ischemia. We report the case of a female patient with ischemic chest pain and third degree atrioventricular block who developed acute myocardial infarction (AMI)

Sixty-eight (17 per cent) of 380 patients with acute myocardial infarction had the bradycardia-hypotension syndrome (ventricular rate below 60/min and systolic blood pressure less than 100 mm Hg) during the first 24 hours of admission to a large general hospital. In 61 of the 68 patients, the

BACKGROUND Due to the increased utilization of this test for the evaluation of chest pain and for prognostic stratification in patients with a recent myocardial infarction, the results of 235 consecutive tests have been analyzed to evaluate the incidence and clinical significance of side effects

The effect of single therapeutic doses of strophanthin (0.25--0.4 mg) and atropine (0.75--1,0 mg) on cardiac contraction was studied in 39 patients with acute myocardial infarction and in 12 subjects with no signs of organic heart affection by recording the electrical potentials of the heart

Heart rate response to intravenous atropine therapy in acute myocardial infarction (MI) was assessed from detailed studies performed on 18 of 492 consecutively admitted coronary care unit patients. Atropine was given for extreme bradycardia (less than 40/min) or bradycardia (less than 60/min)

BACKGROUND Advanced atrioventricular (AV) block is a frequent complication in patients with acute inferior myocardial infarction (AIMI). This conduction abnormality is associated with narrow QRS complex in conducted or junctional escape beats, suggesting that the site of block is the AV node;

OBJECTIVE The aim of this multicenter, multinational, prospective, observational study was to assess the relative value of myocardial viability and induced ischemia early after uncomplicated myocardial infarction. BACKGROUND Dobutamine-atropine stress echocardiography allows evaluation of rest

This study assessed and compared the diagnostic potential of submaximal exercise, transesophageal atrial pacing, dipyridamole, and dobutamine-atropine stress echocardiography tests shortly after acute myocardial infarction. In 121 study patients, 325 digital echocardiographic stress tests were

We report three patients with acute inferior myocardial infarction treated with aspirin (150 mg) and streptokinase (1.5 MU over 60 min), who developed atropine-resistant bradyarrhythmias during or immediately following streptokinase. The bradyarrhythmias responded to aminophylline, thus avoiding the
