BACKGROUND: Non-documented palpitations, or phantom tachycardias, are palpitations deemed to be of unknown origin after evaluation with conventional diagnostic tools, such as 12-lead electrocardiogram and Holter recordings. Our aim was to determine the diagnostic value of an electrophysiologic study (EPS) and its role in the management of patients presenting with non-documented palpitations. METHODS: We performed EPS in 78 consecutive patients with repeatable, poorly tolerated symptoms of paroxysmal, non-documented tachycardia, the absence of structural heart disease and at least one 24-h Holter recording...

BACKGROUND: Premature ventricular contraction (PVC) QRS duration (QRSd) and high PVCs burden are known as a risk factor of PVC-induced cardiomyopathy (CMP). The aim of this study is to find useful algorithm to predict PVC-induced CMP. METHODS: 180 patients (99 males, 51±14years) with frequent PVCs (>10%/24h), who underwent successful PVC ablation, were studied. Typical PVC-related symptoms were defined as the presence of palpitations or dropped beats during PVC...

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 CONCERNS: The patient presented with continuous tachycardia, palpitations, chest tightness, and headache for 4 days, and aggravated for 1 day...

A 45-year-old man with dyspnoea and palpitations exhibited a unique systemic-to-pulmonary veno-venous connection on preoperative CT images. A window of 31.5-mm diameter was evident between the superior caval vein and the middle pulmonary vein, which was normally connected to the left atrium via a 30-mm-diameter orifice. The atrial septum was intact.

 Ephedra Herb is a crude drug for the treatment of headache, bronchial asthma, nasal inflammation, and the common cold. Although it has been considered that ephedrine alkaloids (EAs) are the principal active ingredients of Ephedra Herb, EAs are known to induce palpitations, hypertension, insomnia, and dysuria as major side effects. Therefore, the administration of EAs-containing drugs to patients with cardiovascular-related diseases is strongly contraindicated. Previously, we isolated herbacetin 7-O-neohesperidoside from Ephedra Herb...

Patients with a Pheochromocytoma usually present with intractable hypertension, postural hypotension, headaches and palpitations, with intractable hypertension being the predominant symptom. When the tumor is located in the urinary bladder, symptoms may be induced by micturition. Herein, we report a young patient with a urinary bladder Pheochromocytoma without hypertension or symptoms induced by micturition. Instead, she presented with anemia.

OBJECTIVE: Fibromyalgia (FM) is a chronic disease characterized by widespread pain. Somatic complaints associated with the cardiovascular system, such as chest pain and palpitations, are frequently seen in FM patients. P and QT dispersions are simple and inexpensive measurements reflecting the regional heterogeneity of atrial and ventricular repolarization, respectively. QT dispersion can cause serious ventricular arrhythmias. The aim of the present study was to evaluate QT dispersion and P wave dispersion in patients with FM...

A 90-year-old woman was referred to our hospital because of abdominal distension and pretibial edema. No tumors were palpable in either breast. Her abdomen was distended and palpitation was noticed. Laboratory examination revealed hypercalcemia and elevated levels of tumor markers(PIVKA- II , CEA, CA19-9, SCC). Contrast-enhanced computed tomography(CT) showed pleural effusion and ascites, an approximately 17-mm high-contrast mass in the D area of the left breast, and osteolysis of the dorsal lumber spine. We initiated treatment for pleural effusion, ascites, and hypercalcemia...

Intravenous leiomyomatosis is a rare benign disease. We here in present the case of a 39-year-old woman with a history of hysterectomy who presented with intermittent abdominal pain, palpitations and tightness of the chest. Physical examination revealed the presence of a pelvic mass of regular shape. Gynecological ultrasonography, computed tomography scans and three-dimensional (3D) cardiac ultrasonography were used to evaluate the imaging characteristics of the mass and reach a final diagnosis. The mass appeared to extend to the iliac veins, renal veins and inferior vena cava on imaging examination...

BACKGROUND: Adenosine is the first-line pharmacotherapy for termination of supraventricular tachycardia through its action on the atrioventricular node. However, pro-arrhythmic effects of adenosine are also recognised, most notably in the presence of pre-excited atrial fibrillation. In this case report, we describe the induction of ventricular fibrillation in a patient with no demonstrable accessory pathway, nor any other structural heart disease. This rare, idiosyncratic reaction has never previously been reported and is of relevance given the widespread and routine use of adenosine in clinical practice...

Uterine perforation, a complication of dilation and curettage, is typically recognized immediately after the procedure by clinical symptoms of peritoneal irritation resulting from intraperitoneal bleeding. Our patient complained of having an uncomfortable feeling, slight dizziness, palpitation in the sitting position and abdominal discomfort but did not show signs of peritoneal irritation 24 h after dilation and curettage. However, she suddenly complained of abdominal pain. Tenderness and rebound tenderness were detected at the lower abdominal wall...

Muscular septal aneurysms are extremely rare without a ventricular septal defect and are diagnosed accidentally in most cases. Reported cases generally have rhythm disturbance or electrocardiographic findings of Wolf-Parkinson-White (WPW) syndrome. Presently described are 2 cases of ventricular septal aneurysm associated with WPW syndrome, which presented as dilated cardiomyopathy. Pre-excitation disappeared gradually in first patient. There was also concurrent decrease in degree of bulging of the interventricular septum and improvement of left ventricular systolic function...

Sevil Alan, Betül Ünal, Aytül Yildirim
Isotretinoin has been considered a unique drug for acne treatment. However, it is associated with numerous adverse effects. Isotretinoin can trigger premature ventricular contractions. This report describes a 33-year-old-woman who presented with palpitations for 1 week while undergoing 1-month isotretinoin treatment for mild-moderate facial acne. An electrocardiogram and Holter monitoring showed premature ventricular contractions during isotretinoin (Roaccutane, Roche) treatment. Isotretinoin-related premature ventricular contractions were strongly suggested in this case due to the existence of documented premature ventricular contractions on electrocardiograms and the disappearance of these premature ventricular contractions two weeks after termination of the treatment To the authors' knowledge, there has been 1 reported case of premature ventricular contractions linked to isotretinoin use; this report describes a second such case...
