Electrocardiographic Poor R - Wave
Electrocardiographic criteria have been derived from vectorcardiographic and angiographic correlation which allow division of patients with electrocardiographic “poor R-wave progression” or “reversed K-wave progression” into the following four etiologic groups: (1) anterior myocardial infarction; (2) left ventricular hypertrophy; (3) type-C right ventricular hypertrophy; and (4) the normal vari...
متن کاملPoor R-wave progression.
Poor R-wave progression is a common ECG pattern, which is often inconclusively interpreted by medical directors. Although this ECG pattern is commonly attributed to anterior myocardial infarction, it may also be caused by left bundle branch block, Wolff-Parkinson-White syndrome, right and left ventricular hypertrophy as well as by faulty ECG recording technique. Failure to make a definitive int...
متن کاملPrevalence and Positive Predictive Value of Poor R-Wave Progression and Impact of the Cardiothoracic Ratio
BACKGROUND AND OBJECTIVES Poor R-wave progression (PRWP) is a common electrocardiographic diagnosis. However, the diagnostic usefulness of PRWP for coronary artery disease (CAD) and the plausible explanation for subjects with normal heart function are unclear. SUBJECTS AND METHODS We included 20,739 subjects who had routine medical examinations and applied the commonly used criteria (R-waves ...
متن کاملPoor R wave progression in the precordial leads: clinical implications for the diagnosis of myocardial infarction.
A definite diagnosis of anterior myocardial infarction is often difficult to make in patients when a pattern of poor R wave progression in the precordial leads is present on the electrocardiogram. The purpose of this study was to determine whether a mathematical model could be devised to identify patients with anterior infarction among 102 consecutive patients with poor R wave progression. Each...
متن کاملPoor R-wave progression in the precordial leads in left-sided spontaneous pneumothorax.
A 30-year-old man without any cardiovascular history was transferred to our hospital because of chest pain. On arrival, his blood pressure was 166/93 mm Hg, with a pulse rate of 58 bpm. His oxygen saturation level was 98%. His ECG showed normal sinus rhythm, with poor R-wave progression in the precordial leads (Figure, A). The white blood cell count was 7990/mm, and the level of creatine kinase...
