We describe a neonate that developed alternating wide and narrow complex tachycardias following heart surgery for congenital heart defect. Although the etiology was sinus tachycardia, a premature atrial complex initiated aberrancy due to phase 3 block that was perpetuated due to 'linking' at similar or even slower heart rates. Similarly, there was abrupt transition from wide to narrow complex tachycardia following a premature ventricular complex without a change in subsequent heart rate. This was explained by interruption of linking phenomenon by premature ventricular activation...

OBJECTIVES: This study sought to investigate the utilization of and in-hospital complications in patients undergoing catheter ablation in the United States from 2000 to 2013 by using the National Inpatient Sample and Nationwide Inpatient Sample. BACKGROUND: Catheter ablation has become a mainstay in the treatment of a wide range of cardiac arrhythmias. METHODS: This study identified patients 18 years of age and older who underwent inpatient catheter ablation from 2000 to 2013 and had 1 primary diagnosis of any of the following arrhythmias: atrial fibrillation, atrial flutter, supraventricular tachycardia, or ventricular tachycardia...

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia affecting performance in horses. However, no previous studies have quantified the performance reduction in horses suffering from AF. OBJECTIVES: To quantify the effect of AF on maximum velocity (Vmax ), maximum heart rate (HRmax ), heart rate recovery (T100 ), hematologic parameters and development of abnormal QRS complexes. ANIMALS: Nine Standardbred trotters. METHODS: Two-arm controlled trial...

BACKGROUND AND OBJECTIVE: Automatic processing and accurate diagnosis of wide complex tachycardia (WCT) arrhythmia groups using electrocardiogram signals (ECG) remains a challenge. WCT arrhythmia consists of two main groups: ventricular tachycardia (VT) and supraventricular tachycardia with aberrancy (SVT-A). These two groups have similar morphologies in the realm of ECG signals. VT and SVT-A arrhythmias originate from the ventricle and atrium, respectively. Hence, inaccurate diagnosis of SVT-A instead of VT can be fatal...

BACKGROUND Lown-Ganong-Levine syndrome, includes a short PR interval, normal QRS complex, and paroxysmal tachycardia. The pathophysiology of this syndrome includes an accessory pathway connecting the atria and the atrioventricular (AV) node (James fiber), or between the atria and the His bundle (Brechenmacher fiber). Similar features are seen in enhanced atrioventricular nodal conduction (EAVNC), with the underlying pathophysiology due to a fast pathway to the AV node, and with the diagnosis requiring specific electrophysiologic criteria...

INTRODUCTION: Differentiation of wide QRS complex tachycardia required repeated electrophysiological stimuli and mapping. However, instability of tachycardia would increase the difficulty in differential diagnosis. SYMPTOMS AND CLINICAL FINDINGS: In this paper, we reported a wide QRS tachycardia following ablation of an atrioventricular reentrant tachycardia participated by a poster-septal accessory pathway. Limited differentiation strategy was performed because the wide QRS tachycardia was self-limited and with unstable hemodynamics...

Metoclopramide (MCP) is a commonly used anti-emetic in the emergency department (ED). Its use is generally well tolerated; although infrequent adverse reactions such as extrapyramidal reactions or tardive dyskinesia are reported. However, many ED providers are not familiar with the potentially life-threatening hypertensive emergency that can be precipitated by MCP administration in patients with pheochromocytoma. A previously healthy 36-year-old woman presented to the ED with headache and nausea. She developed acute hypertensive emergency (acute agitation, worsening headache, chest pain and wide complex tachycardia) when her blood pressure (BP) increased to 223/102mmHg (initial BP, 134/86mmHg) after receiving intravenous MCP...

BACKGROUND Intracardiac abscesses are an unusual occurrence in developed countries. With the increase in use of implantable cardiac devices, the increase use of and advancements in antibiotics, and the longevity of patients with cardiac devices, one may expect an increase in such infections; however, case reports are rare. We are presenting a case in which hematogenous dissemination of methicillin-sensitive Staphylococcus aureus (MSSA) infection from a lower extremity diabetic ulcer propagated into an infected pacemaker lead and ultimately an intracardiac abscess of the right atrium...

BACKGROUND: Postural orthostatic tachycardia syndrome (POTS) is a form of orthostatic intolerance, and its incidence in children is approximately 6.8% [1]. The pathogenesis of POTS is complex with multiple, overlapping, interacting pathophysiological mechanisms. Although the specific pathogenic mechanism has remained perplexing, with the discovery of various gasotransmitters and biological peptides, the vascular dysfunction has aroused overwhelming attention. DATA SOURCES: On the basis of searching in a wide range of recent original literatures, we reviewed the pathogenesis of vascular dysfunction in children with POTS...

BACKGROUND Left bundle branch block (LBBB) is associated with atrial fibrillation (AF) and systolic heart failure, which can be treated with cardiac resynchronization therapy (CRT) that includes an implantable cardiac device (ICD). However, in some patients, LBBB may vary with heart rate, and during episodes of AF in LBBB, aberrant ventricular conduction, or wide QRS complex tachycardia (Ashman beats) can occur. This report is a case of LBBB treated with pharmacologic CRT, without the use of an ICD. CASE REPORT A 68-year-old man presented with persistent AF and systolic heart failure...

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is a widely used procedure in the treatment of malignant diseases, including blood neoplasms and has increased survival in hematological diseases. The aim of the study was to analyze parameters of 24-hr ECG monitoring in patients with selected blood neoplasms in whom the procedure of hematopoietic stem cell transplantation was performed. METHODS: The study group consisted of 64 adults diagnosed with hematologic cancer qualified for HSCT with the previous high dose chemotherapy (HDC)...

Min Yu, Tingting Chen, Shuang Hu, Shan Zou, Cantian Wang, Chujuan Zeng, Weijie Chen, Xuerui Tan
BACKGROUND: Recently, the R-wave peak time (RWPT) at lead II was reported to be a helpful and simple tool for differentiating wide QRS complex tachycardias with a RWPT ≥ 50ms for ventricular tachycardia diagnosis. Our previous study showed that the duration of RWPT at lead II in adults was ≈29ms. However, the effects of ventricular premature beats (VPBs), bundle branch block (BBB) or left anterior fascicular block (LAFB) on RWPT at lead II remain unknown. METHODS: The study was conducted in the First Affiliated Hospital of Shantou University Medical College in Southern China...

OBJECTIVE: To date, no systematic work has been intended to describe spatio-temporal patterns of cardiac rhythms using only short series of RR intervals, to facilitate visual or computerized-aided identification of EKG motifs for use in clinical practice. The aim of this study was to detect and classify eye-catching geometric patterns of Poincaré time-delay plots from different types of cardiac rhythms and arrhythmias using short-term EKG signals. METHODS: Approximately 150-300 representative, consecutive beats were retrieved from 24-h Holter registers of 100 patients with different heart rhythms...
