Ethnic differences in ECG amplitudes in North American white, black, and Hispanic men and women. Effect of obesity and age

Autor: P M, Rautaharju, S H, Zhou, H P, Calhoun

Publikováno v: Journal of electrocardiology.

General trends were investigated in the age-evolution of electrocardiogram (ECG) patterns using ECG data of North American white, black, and Hispanic men and women aged 25-74 years, derived from the Second National Health and Nutrition Examination Su

Sex differences in the evolution of the electrocardiographic QT interval with age

Autor: P M, Rautaharju, S H, Zhou, S, Wong, H P, Calhoun, G S, Berenson, R, Prineas, A, Davignon

Publikováno v: The Canadian journal of cardiology. 8(7)

To investigate sex differences in the evolution of the QT interval with age.A community-based representative North American population sample of 14,379 children and adults aged from birth to 75 years. The measured QT intervals (QTm) were determined b

Contemporary medical management of left ventricular dysfunction and congestive heart failure

Autor: K K, Teo, A P, Ignaszewski, R, Gutierrez, K L, Hill, S L, Martin, H P, Calhoun, D P, Humen, T J, Montague

Publikováno v: The Canadian journal of cardiology. 8(6)

The primary purpose of this review was to address the following question: based on the best available evidence, what should be the current medical management of congestive heart failure (CHF)?The major sources for this review were from searches of th

Should the JT rather than the QT interval be used to detect prolongation of ventricular repolarization? An assessment in normal conduction and in ventricular conduction defects

Autor: S H, Zhou, S, Wong, P M, Rautaharju, N, Karnik, H P, Calhoun

Publikováno v: Journal of electrocardiology.

It has been suggested that the JT rather than QT interval properly reflects repolarization duration in ventricular conduction defects (VCD). The authors examined the influence of QRS duration on the JT and QT intervals in 20,687 normal adult subjects

Methodology of ECG interpretation in the Dalhousie program; NOVACODE ECG classification procedures for clinical trials and population health surveys

Autor: P M, Rautaharju, P J, MacInnis, J W, Warren, H K, Wolf, P M, Rykers, H P, Calhoun

Publikováno v: Methods of information in medicine. 29(4)

The Dalhousie ECG Program was designed specifically for the needs of epidemiologic studies, health surveys, and clinical trials. The program logic is dynamic in that it can accommodate any combination of ECG leads, record length and sampling rate. Th

Estimation of QT prolongation. A persistent, avoidable error in computer electrocardiography

Autor: P M, Rautaharju, J W, Warren, H P, Calhoun

Publikováno v: Journal of electrocardiology.

A pooled community-based population sample of 17,139 North American children, adolescents, and adults aged from birth to 75 years was used to evaluate a variety of one-, two-, and three-parameter formulas for correction of the QT interval for heart r

Complexes of Dimethylaminophosphazenes with Metal Ions

Autor: N. L. Paddock, H. P. Calhoun, J. N. Wingfield

Publikováno v: Canadian Journal of Chemistry. 53:1765-1774

The preparation of complexes DDPN.2MCl2 (M = Mn, Fe, Co, Zn ), DDPN.M(NO3)2, (M = Mn, Co, Ni, Cu, Zn), (DDPN = N6P6(NMe2)12) ), and N9P9(NMe2)18.2CoCl2 is described. All the complexes of the hexamer are of the high spin type and contain the cations D
