Oesophageal Pain and Catecholamine Mediated Ecg Changes Mimicking Myocardial Ischaemia

Oesophageal motility, luminal pH, and electrocardiographic-ST segment analysis during spontaneous episodes of angina like chest pain.

The relation between oesophageal motility, luminal pH, and spontaneous pain events in 47 patients with recurrent angina like pain and normal coronary arteries was investigated. Preliminary investigation by conventional station pull through manometry (SPTM), was followed by a 24 hour period of ambulatory oesophageal motility and luminal pH monitoring. Computerised analysis of motility and pH dat...

Oesophageal Pain Mimicking Cardiac Ischaemia

Pseudo-ischaemic ECG in a patient with amyotrophic lateral sclerosis surviving for a decade.

A 58-year-old female with no history of heart disease was admitted to our hospital for abnormal ECG mimicking myocardial ischaemia. The ECG revealed persistent T-wave inversion in almost all leads, especially in precordial leads V2-V6. The patient had no complaints of chest pain, chest distress, short of breath or other atypical myocardial ischaemia symptoms. She had a history of amyotrophic la...

Silent myocardial ischaemia in patients with proved coronary artery disease: a comparison of diabetic and non-diabetic patients.

OBJECTIVE To determine whether diabetic patients with coronary artery disease are more likely to experience silent myocardial ischaemia than subjects without diabetes. SUBJECTS Patients undergoing coronary angiography at a regional cardiothoracic unit, identified as having diabetes from the local district diabetic register/database. DESIGN The coronary angiograms and exercise treadmill test...

ECG record during changes in oesophageal pH.

Seventeen patients with non-cardiac chest pain were investigated by simultaneous ambulatory 24 hour ECG and oesophageal pH monitoring. While 11 patients lowered their oesophageal pH below 4 for a significant percentage, (3.4%) of recorded time and experienced chest pain, no simultaneous ECG changes occurred. In 10 patients chest pain was reproduced by an oesophageal acid perfusion test (Bernste...
