Characterization of Ischemia Related Changes in Esophageal Electrocardiography

NCT01390155 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 45

No results posted yet for this study

Summary

Esophageal electrocardiography (eECG) has important advantages compared to standard ECG recordings.

Coronary artery disease leading to myocardial ischemia is very common and has potentially severe consequences for patients. To date, the investigators don't know the influence of ischemia on the eECG. The goal of the present study is to assess ischemic changes of the eECG induced by balloon occlusion of coronary arteries in patients undergoing coronary angiography.

Conditions

Interventions

PROCEDURE

Measurement of coronary collateral flow index

One-minute balloon occlusion of the proximal left anterior descending coronary artery inducing a controlled short-time ischemic condition of a part of the myocardium and simultaneous evaluation of collateral flow.

PROCEDURE

Measurement of coronary collateral flow index

One-minute balloon occlusion of the proximal left circumflex artery inducing a controlled short-time ischemic condition of a part of the myocardium and simultaneous evaluation of collateral flow.

PROCEDURE

Measurement of coronary collateral flow index

One-minute balloon occlusion of the proximal right coronary artery inducing a controlled short-time ischemic condition of a part of the myocardium and simultaneous evaluation of collateral flow.

PROCEDURE

Measurement of coronary collateral flow index

One-minute balloon occlusion of the target vessel (the vessel which shows a significant stenosis and accordingly requires a therapeutical intervention by balloon angioplasty and stenting) inducing a controlled short-time ischemic condition of a part of the myocardium and simultaneous evaluation of collateral flow.
