The differential diagnosis for wide complex tachycardia includes all causes of narrow complex tachycardia with bundle branch block, all causes of narrow complex tachycardia with antegrade pre-excitation, ventricular tachycardia, and antidromic and other pre-excited reciprocating tachycardias. The variation in a specific intracardiac interval that causes a subsequent change in the tachycardia cycle length or another intracardiac interval can be diagnostic in these arrhythmias.

Department of Pathology, Kayseri City Training and Research Hospital, 38080 Kayseri, Turkey.
Background: Lymphomas, which originate from the haematopoietic system, are seldom found in the heart due to the absence of a lymphoid system. Primary cardiac lymphoma is quite rare. Cardiac lymphomas can present with dyspnoea, heart failure, pericardial effusion, and arrhythmia.

Post-acute SarS-Cov2 (PASC), Myalgia encephalomyelitis/Chronic fatigue syndrome (ME/CFS) and Post-acute infection syndrome (PAIS) consist of chronic post-acute infectious syndromes, sharing exhaustive fatigue, post exertional malaise, intermittent pain, postural tachycardia and neuro-cognitive-psychiatric dysfunction. However, the concerned shared pathophysiology is still unresolved in terms of upstream drivers and transducers. Also, risk factors which may determine vulnerability/progression to the chronic phase still remain to be defined.

Background: The diagnostic role of signal-averaged ECG (SAECG) in arrhythmogenic right ventricular cardiomyopathy (ARVC) has lately been questioned. We assessed the value of SAECG-derived late ventricular potentials (LP) in ARVC diagnosis and its association with disease manifestations.
Methods And Results: Patients with definite ARVC diagnosis or genotype-positive family members who underwent SAECG were included in register-based observational study (n=357, mean age 41 years, 47% female, 43% probands).

An elderly lady without any comorbidities, presented with paroxysmal palpitations and was documented to have an adenosine-responsive narrow complex tachycardia (NCT). Baseline electrocardiogram (ECG) showed normal sinus rhythm with no preexcitation. Tachycardia ECG showed a regularly irregular short RP NCT at the rate of around 150/min with alternating cycle lengths of 320 ms and 360 ms.
