TL;DR: Ischemic heart disease (IHD) is one of the leading causes of death in the general population and many analyzing methods using magnetocardiography for the diagnosis are reported.

TL;DR: This small study aims to clarify the status of the efficacy of implantable cardioverter‐defibrillator (ICD) and cardiac‐resynchronization therapy with implantable defibrillators (CRT‐D) in patients with left ventricular dysfunction.

TL;DR: The clinical and electrophysiological characteristic of ventricular premature contractions which trigger the incessant form of polymorphic ventricular tachycardia, and the possible role of the Purkinje network in the emergence of an electrical storm are evaluated.

TL;DR: The intramyocardial and/or periarterial Purkinje cells were recognized in 8 species out of 10, but not in human and dog hearts, while the ordinary subendocardial Purinje cells existed in all hearts examined.

TL;DR: PVC was significantly reduced in the patients with or without underlying diseases (UD), and the reduction rate in the number of PVCs was prominent in patients with UD and in patients without medication.

TL;DR: A case with adenosine‐sensitive focal AT which was successfully ablated at the uncommon focus located at the mitral annulus‐aorta junction is described.

TL;DR: A 15‐year old female in whom an idiopathic ventricular tachycardia originating from the left aortic sinus cusp was eliminated by radiofrequency catheter ablation (RFCA) under navigation using a noncontact mapping system (NCM).

TL;DR: Pulmonary vein isolation is the electrophysiological endpoint of complete conduction block at the level of the veno‐atrial junction and must be explicitly distinguished from encircling PV ablation which frequently does not result in isolation.

TL;DR: After cessation of pilsicainide, incessant wide QRS tachycardia spontaneously subsided and intraventricular conduction delay with coved type ST segment elevation in V1 and V2 disappeared.

TL;DR: This work has shown that excitation of the atrial muscle is propagated from the left atrium (LA) to the PVs, and vice versa, and that electrical impulse conduction from the LA to thePVs is blocked.

TL;DR: A patient in whom stabilization of the LV lead was obtained by placing a coronary stent in the coronary sinus wall which resulted in an improved clinical course is reported on.

TL;DR: The usefulness of Bepridil, which exhibits a class III‐like effect, for class I drug‐induced AFL in patients with paroxysmal AF is studied.

TL;DR: This review has attempted to both highlight a cost‐effective diagnostic pathway beginning with the initial evaluation of the patient with suspected syncope, and to provide criteria which may help frontline physicians better base their decisions regarding need for in‐hospital versus outpatient clinic evaluation of syncope patients.

TL;DR: The effect of nifekalant on life‐threatening ventricular arrhythmias is evaluated and the clinical background between the effective and non‐effective patients is compared in order to clarify the clinical factors which may have an influence on the efficacy of the agent.

TL;DR: A 29‐year‐old male who underwent a complete tetralogy of Fallot repair at 2 years of age was referred to the authors' hospital for treatment of sustained ventricular tachycardia and is free from any VT recurrence during 6 months of follow up.

TL;DR: A 74‐year‐old man presented with palpitation and 12‐lead ECG exhibited atrial premature contraction (APC) at general check‐up and persistent left superior vena cava (LSVC) draining into the right atrium via the markedly dilated coronary sinus was disclosed.

TL;DR: Findings suggest that the presence of rapid activated firing is likely to be associated with the development of instability in the AT circuit, and may lead to a greater understanding of the physiology of atrial tachyarrhythmia as a simple clinical model.

TL;DR: The conditions of AED use in hospital and the prognosis of these patients and the safety and efficacy of automated external defibrillators in the hospital were examined.

TL;DR: A 72‐year-old man with idiopathic dilated cardiomyopathy, who was in New York Heart Association class III and had left ventricular (LV) dyssynchrony on tissue Doppler imaging, might have been positive factors determining this patient's response to CRT.

TL;DR: Three dimensional electroanatomical map integrated with CT imaging clearly revealed the radial activation pattern originating from the basalo‐postero‐inferior aspect of the left atrial appendage that eliminated tachycardia permanently.

TL;DR: The NSAT was eliminated by a radiofrequency energy application to the identified tachycardia focus during sinus rhythm, and the patient has been free from any symptoms during 10 months of follow‐up.

TL;DR: The interactions between the autonomic nervous system and atrial fibrillation are more complex than currently understood and further mechanistic and clinical studies are warranted.

TL;DR: It is found that the ECG detected by the AED fell outside the device's parameters for ventricular tachycardia (VT) or VF, and it is emphasized that the Aed is an excellent device, but it should also be aware of its limitations.

TL;DR: It is of urgent need to have a registry of Asian ARVD/C patients and to conduct a more detailed genetic survey on the candidate genes, including desomosomal ones.

TL;DR: A triphasic circadian pattern with maximum peaks in early morning, late afternoon, and night in SHD, suggesting an association with not only a vagally induced origin but also a sympathecally induced or stress triggered origin in PAF onset inSHD.

TL;DR: A 67‐year‐old male with dilated cardiomyopathy and chronic renal failure who received chronic hemodialysis for 9 years admitted with pulmonary edema and combined cardiac resynchronization therapy and implantable cardioverter defibrillator device was implanted for the secondary prevention of VF.

TL;DR: A permanent transvenous pacemaker with a more physiological rate response function with dual sensors was selected for the bradyarrythmia and the patient was able to resume his active daily life.

TL;DR: A 70-year-old man with persistent atrial fibrillation lasting for 3 months who underwent radiofrequency catheter ablation during on-going AF under navigation using a noncontact mapping system (NCM) has had no recurrence during 10 months of follow-up without taking any antiarrhythmic agents.

TL;DR: A 27 year‐old man was taken to the authors' emergency room after collapsing during a conference andCardioinhibitory type neurocardiogenic syncope was considered to be the cause of the syncope and he was treated with oral disopyramide at a daily dose of 150 mg.

TL;DR: Focal atrial tachycardia (AT) is sometimes associated with sick sinus syndrome and a 57‐year‐old female complained of palpitation, fatigue and presyncope, and underwent electrophysiologic study and radiofrequency catheter ablation to eliminate AT.
