Background: Bidirectional ventricular tachycardia is a rare form of ventricular arrhythmia, characterized by a changing of the mean QRS axis of 180 degrees. Digitalis toxicity is the most common cause of bidirectional ventricular tachycardia; other causes include myocarditis, aconite toxicity, metastatic cardiac tumor, myocardial infarction, and cardiac channelopathies. Case Report: A 73-year-old male with hypertension and a pacemaker implanted for sick sinus syndrome presented with a complaint of substernal chest pressure for several days...

A number of rare cardiac diseases can be recognized by electrocardiogram (ECG). This article illustrates the clinical importance of ECG as a key diagnostic tool to detect Wolff-Parkinson-White syndrome and channelopathies, which are frequently diagnosed late after one or more affected family members have become victims of sudden cardiac death. These channelopathies include long QT syndrome, short QT syndrome, Brugada syndrome, and catecholaminergic polymorphic ventricular tachycardia. In addition, typical ECG findings are frequently present in patients with idiopathic ventricular tachycardia, arrhythmogenic right ventricular dysplasia, digitalis intoxication, hyperkalemia, acute cor pulmonale due to pulmonary embolism, as well as severe left ventricular hypertrophy as in hypertrophic cardiomyopathy...

CONTEXT: Accidental ingestion of foxglove (Digitalis purpurea) can cause significant cardiac toxicity. We report a patient who ingested foxglove mistaking it for comfrey and developed refractory ventricular arrhythmias. The patient died despite treatment with digoxin-specific antibody fragments (DSFab) and veno-arterial extracorporeal membrane oxygenation (VA-ECMO). CASE DETAILS: A 55-year-old woman presented to the emergency department with nausea, vomiting and generalized weakness eight hours after drinking "comfrey" tea...

A 58 years healthy old woman was admitted to the Emergency Department (ED) with cardiac arrest due to ventricular fibrillation (VF). Appropriate cardiopulmonary resuscitation (CPR), multiple DC shocks and oro-tracheal intubation (OTI) were effective to induce recovery of spontaneous circulation (ROSC). After ROSC was achieved, the electrocardiogram (ECG) showed an idio-ventricular rhythm with atrioventricular dissociation. A transcutaneous pacing was hence applied and the patient was administered with isoproterenol...

Bidirectional ventricular tachycardia (BDVT) is a well-known phenomenon since it was first described in 1922. Various mechanisms have been proposed for BDVT, including digitalis toxicity, hypokalemia, Anderson-Tawil syndrome, acute myocarditis, and catecholaminergic polymorphic ventricular tachycardia. It is characterized by rapid, wide complex electrocardiogram pattern with alternating QRS morphology and axis. The alternation of the QRS is usually right bundle branch block with 180° swings in the frontal plane axis or, less commonly, alternation of right bundle branch and left bundle branch forms...

AIMS: Interaction between dronedarone and digitalis has been discussed as a possible cause for increased mortality in the presence of dronedarone observed in the PALLAS trial. The aim of this study was to assess possible proarrhythmic effects of dronedarone in combination with digitalis in an experimental whole heart model. METHODS AND RESULTS: Twenty-six female rabbits underwent chronic oral treatment with dronedarone (50 mg/kg/day for 6 weeks). Twenty-four rabbits received placebo...

UNLABELLED: Patients with heart failure are, by definition, hemodynamically unstable. This condition may be accentuated by medication (digitalis, diuretics, antiarrhythmics), so that they become more sensitive to electrolyte disturbances. Hyponatremia is the most common electrolyte disorder, particularly common in the intensive care unit. AIM: The evaluation of the incidence of hyponatremia in patients diagnosed with chronic heart failure in order to establish a correlation with the evolution, prognosis and therapeutic implications...

BACKGROUND: Short QT syndrome (QTc ≤ 300 ms) is a novel hereditary channelopathy linked to syncope, paroxysmal atrial fibrillation, and sudden cardiac death. However, its epidemiological features remain unsettled. OBJECTIVES: (1) To assess the prevalence of short QT in a large population-based sample; (2) to evaluate its demographic and clinical correlates and; (3) to determine its prognosis. METHODS: A database of 6.4 million electrocardiograms (ECGs) obtained between 1995 and 2008 among 1...

OBJECTIVE: Recently, we reported that low-dose landiolol (1.5 µg·kg(-1)·min(-1)), an ultra-short-acting β-blocker, safely decreased the heart rate (HR) in patients with acute decompensated heart failure (ADHF) and sinus tachycardia, thereby improving cardiac function. We investigated whether low-dose landiolol effectively decreased the HR in ADHF patients with rapid atrial fibrillation (AF). METHODS: We enrolled 23 ADHF patients with rapid AF (HR ≥120 beats·min(-1) and New York Heart Association class III-IV) and systolic heart failure (SHF: n = 12) or diastolic heart failure (DHF: n = 11) who received conventional therapy with diuretics, vasodilators, and/or low-dose inotropes...

BACKGROUND: The underlying cause of a high cardiovascular event rate in the population with low diastolic blood pressure (DBP) has not been fully elucidated. METHODS AND RESULTS: The relationship between DBP and ischemia-like findings on electrocardiography (ECG) was investigated in 187 patients who underwent coronary angiography. Patients with conditions affecting ECG (e.g. patients taking digitalis or those with old myocardial infarction, complete right bundle branch block, or hypokalemia) were excluded from the analyses...

Plant poisonings are rare in Denmark, but can have fatal consequences. We present a case in which a woman went into cardiac arrest after having ingested leaves from the foxglove plant. Sinus rhythm was not restored until Digibind was administered. Literature in this field is sparse, but we conclude that the following advice can be given: 1) assessment of the degree of poisoning should be based on clinical features and changes of the electrocardiogram; 2) activated charcoal should be given; 3) in case of malignant arrhythmia or cardiac arrest, the use of Digibind should be considered...

Hypokalemia is common and can be associated with serious adverse consequences, including paralysis, ileus, cardiac arrhythmias, and death. As a result, the body maintains serum potassium concentration within very narrow limits by tightly regulated feedback and feed-forward systems. Whereas the consequences of symptomatic hypokalemia and severe potassium depletion are well appreciated, chronic mild hypokalemia can accelerate the progression of chronic kidney disease, exacerbate systemic hypertension, and increase mortality...

BACKGROUND: Hypothyroidism is a reversible cause of atrioventricular (AV) block. Few reports have described reversible AV block caused by hyperthyroidism. However, it is unknown whether patients with AV block are expected to have a benign course after the initiation of appropriate therapy for thyroid dysfunction. METHODS: The study group consisted of patients with II or III degree AV block and bradyarrhythmia (≤40bpm) excluding patients with myocardial infarction, electrolyte abnormalities, digitalis toxicity, and vasovagal syncope...
