The Effect of Age, Blood Pressure and Gender on the Incidence of Premature Ventricular Contractions
- Coronary Arteritis. Brooks, Matthew J.; Iyer, Ravi // New England Journal of Medicine;8/16/2012, Vol. 367 Issue 7, p658
The article describes a case of coronary arteritis in a 25-year-old female patient. The woman, who had just undergone cardiac arrest due to ventricular fibrillation, was brought to the hospital and was thereafter successfully resuscitated and cooled. Her serial electrocardiography showed marked...
- Salvage assessment with cardiac MRI following acute myocardial infarction underestimates potential for recovery of systolic strain. O'Regan, Declan; Ariff, Ben; Baksi, A.; Gordon, Fabiana; Durighel, Giuliana; Cook, Stuart // European Radiology;May2013, Vol. 23 Issue 5, p1210
Objectives: Our aim was to evaluate the relationship between the degree of salvage following acute ST elevation myocardial infarction (STEMI) and subsequent reversible contractile dysfunction using cardiac magnetic resonance (CMR) imaging. Methods: Thirty-four patients underwent CMR examination...
- A hybrid wavelet and time plane based method for QT interval measurement in ECG signals. Majumder, Swanirbhar; Pal, Saurabh; Dhar, Sidhartha; Sinha, Abhijit; Roy, Abhijit // Journal of Biomedical Science & Engineering;Aug2009, Vol. 2 Issue 4, p280
Here we present a method of QT interval measurement for Physionet's online QT Challenge ECG database using the combination of wavelet and time plane feature extraction mechanisms. For this we mainly combined two previous works one done using the Daubechies 6 wavelet and one time plane based with...
- Beat-to-Beat Variation of the ST Segment in a Patient with Right Bundle Branch Block, Persistent ST Segment Elevation, and Ventricular Fibrillation. Hirata, Kazuhito; Takagi, Yousuke; Nakada, Misao; Kyushima, Masahiro; Asato, Hiroaki // Angiology;Jan1998, Vol. 49 Issue 1, p87
The authors describe a patient with ventricular fibrillation associated with right bundle branch block-like QRS morphology and persisting ST segment elevation in the precordial leads, in whom the morphology of the ST segment changed from the coved type to the saddle-back type or vice versa on a...
- Precordial exercise mapping: improved diagnosis of coronary artery disease. // British Medical Journal;12/9/1978, Vol. 2 Issue 6152, p1596
Presents a study on surface mapping of the exercise electrocardiogram for improved diagnosis of coronary artery disease. Effects on the ST-segment occuring after exercise; Techniques of precordial surface mapping; Effect on the coronary artery.
- Electrocardiographic chest wall mapping in the diagnosis of coronary artery disease. Salmasi, A.M.; Nicolaides, A.N.; Vecht, R.J.; Hendry, W.G.; Salmasi, Sajida N.A.; Nicolaides, E.P.; Kidner, P.H.; Besterman, E.M.M. // British Medical Journal (Clinical Research Edition);7/2/1983, Vol. 287 Issue 6384, p9
Discusses the important aspects of electrocardiography in the determination of coronary artery disease. Processes in chest wall mapping; Detection of coronary artery disease; Reliability of the diagnostic procedure.
- Exercise ECG in women: How to increase diagnostic accuracy. // Geriatrics;Oct97, Vol. 52 Issue 10, p16
Examines the importance of examining the QT dispersion (QTD) component of an exercise electrocardiogram (ECG) to accurately diagnose coronary artery disease in women, according to Ramdas G. Pai, staff cardiologist and director of echocardiography and outpatient cardiology. Results of the study...
- Systolic and diastolic blood pressures as predictors of coronary heart disease in middle aged Norwegian men. Tverdal, Aage // British Medical Journal (Clinical Research Edition);3/14/1987, Vol. 294 Issue 6573, p671
Analyzes systolic and diastolic blood pressures as predictors of coronary heart disease in several men in Norway. Relationship between human blood pressure and age; Association of death from coronary heart disease with obesity; Emphasis on the systolic pressure in the diagnosis.
- The tooth, the whole tooth, and nothing but the tooth: can dental pain ever be the sole presenting symptom of a myocardial infarction? A systematic review. // British Dental Journal;6/13/2014, Vol. 216 Issue 11, p639
Despite frequent claims to the contrary, there is little evidence that dental pain could be the only symptom for cardiac insufficiency.
