ECG Blog #411 — Is it Wenckebach?

Ken Grauer, MD

How would YOU interpret the tracing in Figure-1 — that was sent to me without additional information? QUESTIONS: What is the rhythm? Is there AV dissociation? If so — WHY? Clinically — HOW would you approach interpretation of this tracing in optimal time -efficient fashion? Figure-1: The initial ECG in today's case. KEY Clinical Point: If I was the medical provider charged with the care of the patient whose ECG is shown in Figure-1 — I would approach this tracing in the following sequential stag

Cardiovascular autonomic dysfunction in post-COVID-19 syndrome: a major health-care burden

Nature Reviews - Cardiology

Nature Reviews Cardiology, Published online: 02 January 2024; doi:10.1038/s41569-023-00962-3 Cardiovascular autonomic dysfunction (CVAD) is a malfunction of the autonomic control of circulatory homeostasis and is an important component of post-COVID-19 syndrome. In this Review, Fedorowski and colleagues define the major forms of CVAD (including postural orthostatic tachycardia syndrome), and discuss the aetiology, diagnosis and management of post-COVID-19 syndrome-associated CVAD.

Single-cell transcriptomics and chromatin accessibility profiling elucidate the kidney-protective mechanism of mineralocorticoid receptor antagonists

Journal of Clinical Investigation - Cardiology

Mineralocorticoid excess commonly leads to hypertension (HTN) and kidney disease. In our study, we used single-cell expression and chromatin accessibility tools to characterize the mineralocorticoid target genes and cell types. We demonstrated that mineralocorticoid effects were established through open chromatin and target gene expression, primarily in principal and connecting tubule cells and, to a lesser extent, in segments of the distal convoluted tubule cells.

CDKL5 regulates p62-mediated selective autophagy and confers protection against neurotropic viruses

Journal of Clinical Investigation - Cardiology

Virophagy, the selective autophagosomal engulfment and lysosomal degradation of viral components, is crucial for neuronal cell survival and antiviral immunity. However, the mechanisms leading to viral antigen recognition and capture by autophagic machinery remain poorly understood. Here, we identified cyclin-dependent kinase–like 5 (CDKL5), known to function in neurodevelopment, as an essential regulator of virophagy.

Gasdermin C sensitizes tumor cells to PARP inhibitor therapy in cancer models

Journal of Clinical Investigation - Cardiology

Several poly (ADP-ribose) polymerase (PARP) inhibitors (PARPi) are approved by FDA to treat cancer with BRCA mutations. BRCA mutations are considered to fuel a PARPi killing effect by inducing apoptosis. However, resistance to PARPi is frequently observed in the clinic due to an incomplete understanding on the molecular basis of PARPi function and a lack of good markers, beyond BRCA mutations, to predict response.

Targeting lysine demethylase 6B ameliorates ASXL1 truncation–mediated myeloid malignancies in preclinical models

Journal of Clinical Investigation - Cardiology

ASXL1 mutation frequently occurs in all forms of myeloid malignancies and is associated with aggressive disease and poor prognosis. ASXL1 recruits Polycomb repressive complex 2 (PRC2) to specific gene loci to repress transcription through trimethylation of histone H3 on lysine 27 (H3K27me3). ASXL1 alterations reduce H3K27me3 levels, which results in leukemogenic gene expression and the development of myeloid malignancies.
