According to the criteria of Vasan and Levy diagnosis of diastolic heart failure is probable, if symptoms and signs of heart failure are accompanied in proximity (within 72 h) by objective evidence of normal left ventricular systolic function. Newer echocardiographic techniques (e. g., tissue ...
The selection criteria were as follows: over 18 years of age; apparently normal ECG; no acute or old MI; no previous percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). An apparently normal ECG is defined by the following [30]: 1) heart rate between 55 and...
Multiple criteria have been proposed to diagnose LV hypertrophy using necropsy or echocardiographic information (Table 3 and Table 4). Of these, the Sokolow-Lyon criterion (SV1 + RV5,6 _35 mm) is the most specific (>95 percent) but is not very sensitive (45 percent) (see Table 4). ...
Introduction:\nCardiac resynchronization therapy (CRT) is beneficial in patients with heart failure with reduced ejection fraction and normal sinus rhythm. However, its role in patients with pacing indication, narrow QRS, and normal ejection fraction remains controversial.Objectives:\nWe aimed to ...

Criteria for patient enrollment into the PEP-CHF study, however, also had shortcomings. The diagnosis of symptomatic HF was linked to 9 criteria, of which 3 needed to be satisfied. These criteria comprised, among others, prior myocardial infarction and a cardiothoracic ratio >0.55. As a result...
electrocardiographic patterns consistent with a left ventricular site of origin.J Am Coll Cardiol1997,29:1023–1027. Investigation of a series of patients with either RVOT tachycardia or LVOT tachycardia with characterization of ECG criteria to aid in the diagnosis. Tachycardias with a precordial R-...
Hypertension was defined as a systolic blood pressure of 160 mm Hg or higher or a diastolic blood pressure of 100 mm Hg or higher or the use of blood pressure–lowering drugs prescribed for hypertension, encompassing grades 2 and 3 hypertension, according to World Health Organization criteria. ...
The sleep state (REM or quiet) was determined using neurophysiologic and be- havioral criteria. The results of regression analyses indicated that the delta RR values were positively correlated with the instanta- neous heart rate (RR intervals). The correlation coefficient range was 0.49 to 0.92...
