The electrocardiographic phenomenon of cardiac memory results from aberrant ventricular activation and causes transient ECG features that can mimic ischaemia. We present the case of a patient with ischaemic cardiomyopathy who exhibited evidence of T-wave memory in the setting of multiple episodes of non-sustained ventricular tachycardia that were triggered by an insect bite.

BACKGROUND Early injection of atropine during dobutamine stress echocardiography has been demonstrated in retrospective analyses to reduce the duration and dose of dobutamine infusion, while preserving a similar diagnostic accuracy with a lower incidence of adverse effects. AIM In our prospective study, we sought to explore the safety of the early atropine-dobutamine stress echocardiography p...

Intravenous ephedrine administered during a C-section was observed to cause an acute coronary syndrome in a pregnant woman with normal coronaries. The patient developed sub-sternal chest pain, was noted to have 10 beats of non-sustained ventricular tachycardia, ST abnormalities were observed on her ECG and cardiac enzymes were elevated. The patient had normal coronary arteries by angiogram and ...

The difference in sympathovagal activity preceding non-sustained ventricular tachycardia (NSVT) was examined between patients with and without a circadian rhythm. Thirty-three patients' Holter monitoring data (41 NSVT episodes) were analyzed regarding the frequency domain measures (low-frequency component [LF: 0.04-0.15 Hz], high-frequency component [HF: 0.15-0.4 Hz], and the ratio of LF to HF ...

A 28 year old white woman with no medical history presented to the emergency room with symptomatic non-sustained ventricular tachycardia. She was asymptomatic up to a few days before presentation. Her physical examination was essentially normal and hence did not help with the differential diagnosis of the problem. Bronchoscopic transbronchial biopsy led to the final diagnosis of cardiac sarcoid...

We describe a case of amiodarone-induced thyrotoxicosis (AIT) with cardiopulmonary arrest (CPA) in a 49-year-old woman. The patient had been treated with amiodarone for non-sustained ventricular tachycardia. Two weeks prior to her admission, she developed thyrotoxicosis and prednisolone (PSL, 30 mg daily) was administered with the continuation of amiodarone. However, she was admitted to our hos...

purpose: to evaluate the effect of intravitreal bevacizumab (ivb) injection on sustained intraocular pressure (iop) methods: this non-randomized prospective study was conducted on 359 eyes of 359 patients in amir almomenin (rasht) and labbafinejad (tehran) hospitals. after history taking and complete ocular examination, iop was measured one week and one day before injection (twice at each sessi...

Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...

This study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. Bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. The immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...

Frequent dosing of the potent anti-androgen, flutamide, is necessary to reach a therapeutic level for the treatment of prostatic carcinoma. Sustained delivery of the drug could reduce the adverse effects such as gastrointestinal disorders and improve patient compliance. In the present study sustained-release matrix tablets of flutamide were prepared by direct compression method using different ...
