Transient entrainment was demonstrated during 59 pacing events in 18 episodes of sustained uniform ventricular tachycardia (VT) while recording electrograms from the site of origin of tachycardia (LE-SOO). During entrainment, the morphology of the initial component of the LE-SOO was identical to the morphology observed during the tachycardia in 13 VTs (group I), but in five VTs (group II), the ...

adonis aestivalis (summer pheasant-eye) is an annual plant with a crimson flower, distributed in southern europe and asia. the plant has large buttercup-like blossoms and soft, fern-like leaves. it blooms in spring and is often found as a weed in cereal fields. like other adonis spp., the plant produces cardiac glycosides. it is used in remedies for mild weakness of the heart, especially when a...

Background: Slow coronary flow (SCF) is defined as a condition in which in spite of no evidence of coronary occlusion or stenosis in angiography, there is delayed pacification of the vessels after the injection of a contrast agent. There are several studies about electrocardiogram (ECG) changes in these patients, but changes like OLD MI, RBBB, LBBB, LVH and ST-T wave have not b...

• Concern has been expressed repeatedly in the electrocardiographic literature as to whether the three leads of a spatial vectorcardiogram contain more or less information than that found in the standard twelve-lead electrocardiogram." Frequently the adequacy of the report of the twelve-lead electrocardiogram has also been questioned and addition of one or more exploratory leads has been recomm...

RATIONALE Dome-and-dart T waves (or bifid T waves) are a rare phenomenon in the surface electrocardiogram. These wave forms are mainly observed in patients with congenital heart disease such as atrial septal defect and ventricular septal defect. And hyperthyroidism who presented with an electrocardiogram that had dome-and-dart T waves in a precordial lead is never been reported. PATIENT CONCE...

Of i8 patients admitted to hospital with proved viral (influenza A, echo-9 and -30) or Mycoplasma pneumoniae infections, 6young adults between I5 and27years showed electrocardiographic evidence ofsymptomless myocarditis, which was invariably associated with myalgia. Myalgia is an important symptom presaging myocarditis and is an indication for an early electrocardiogram in all patients with sus...

introduction atrial standstill is a rare condition, characterized by absence of atrial electrical and mechanical activity evident in surface electrocardiography echocardiography, or fluoroscopy, which is associated with unresponsiveness of atria to maximal output electrical stimulation. this condition can be present with thromboembolic complication, low cardiac output, and sometimes palpitation...
