BACKGROUND The value of the 12-lead electrocardiogram (ECG) to provide prognostic information in the deadly and disabling syndrome peripartum cardiomyopathy (PPCM) is unknown. AIMS To determine the prevalence of major and minor ECG abnormalities in PPCM patients at the time of diagnosis, and to establish whether there are ECG correlates of persistent left ventricular dysfunction and/or clinic...

Hospital Physician September 2007 15 E lectrocardiography is a valuable, noninvasive graphical representation of the heart’s electrical activity. Augustus D. Waller, a physiologist from London, published a description of the first human electrocardiogram (ECG) in 1887,1 and since then, the ECG has evolved as a useful tool in diagnosing coronary artery disease, rhythm abnormalities, and certain ...

wave amplitudes in appropriate leads of the resting ECG, was ascertained among 2,760 survivors of myocardial infarction who had been randomized into the placebo-treated group of the Coronary Drug Project. The entry ECG findings were related to the subsequent three-year mortality. Of 2,760 men, 186 (6.7%) had ECG-LVH amplitude criteria in the baseline ECG when taken after at least three months s...

BACKGROUND Although cardiovascular screening is recommended for athletes before participating in sports, the role of 12-lead electrocardiography (ECG) remains uncertain. To date, no prospective data that compare screening with and without ECG have been available. OBJECTIVE To compare the performance of preparticipation screening limited to medical history and physical examination with a strat...

Various electrocardiography (ECG) abnormalities have been reported in patients who present with pulmonary embolism (PE). Severe sepsis is also associated with ECG changes that may mimic ST elevation myocardial infarction. We report a case of an elderly patient with PE and septic shock associated with striking ECG changes.

Before attempting any signal processing of the electrocardiogram it is important to first understand the physiological basis of the ECG, to review measurement conventions of the standard ECG, and to review how a clinician uses the ECG for patient care. The material and figures in this chapter are taken from [1, 2], to which the reader is referred for a more detailed overview of this subject. Fu...

BACKGROUND AND OBJECTIVES A high risk of cardiac arrhythmias was reported in myotonic dystrophy type 1 (DM1). The purpose of the study was to evaluate the risk of severe electrocardiographic abnormalities in DM1 patients with small CTG expansions. METHODS We assessed the ECG done at DM1 diagnosis for 127 patients with ≤200 CTG repeats and for 82 of them who had ≥1 ECG over a period of follow-...
