Aims: This study is focused on the types of arrhythmias that cause cardiac failure, and answers to these questions may eventually offer public awareness and clinical information to help develop preventive measures that can reduce SCD risks induced by arrhythmias in patients undergoing dialysis. Methodology: This systematic review and meta-analysis followed the guidelines provided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The reviewers searched the Cochrane Library, MEDLINE, Europe PMC, and Google Scholar Databases for relevant data sources. We included only randomized controlled trials and cohort studies published in English. A quantitative analysis (meta-analysis) was conducted using Review Manager version 5.4 (RevMan 5.4; The Nordic Cochrane Center, The Cochrane Collaboration, 2014). Results: The initial database search yielded 547 studies, of which 213 duplicates were excluded. The title, abstract, and full-text screening excluded 247 studies, and the final total included 13 studies reporting the incidence of SCD mortality in this meta-analysis. SCD remains a major public health concern, particularly in patients undergoing dialysis. Meta-analysis results show that bradyarrhythmia emerges as a common type of arrhythmia leading to SCD; however, other types of arrhythmias should also be considered.

Background: Dialysis is an intervention used chiefly to cover poorly functioning kidneys' ultrafiltration and diffusion functions. Dialysis can be performed using three major approaches: peritoneal dialysis, hemodialysis, and continuous renal replacement therapy, which have varying degrees of efficiency. We sought to compare the mortality rates among patients receiving different dialysis modalities. Study Design: Statistical Review and Meta-Analysis. Setting & Population: The investigation was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Data sources were drawn from Google Scholar, ResearchGate, PubMed (MEDLINE), Cochrane Library, and Embase databases. Eligible patients had to be ones presenting with acute or chronic kidney failure who required assistance with kidney function. Selection Criteria for Studies: The eligibility criteria included studies with participants requiring dialysis and comparing two of the three dialysis modalities that provided outcomes on mortality rates. Inclusion criteria (underlying disease, chronic or acute kidney disease, presenting signs, age categories, subject consent, etc.), the type of dialysis modalities under investigation, and the mortality rates (% per modality group). Index Texts: 'mortalities, fatalities, dialysis, hemodialysis, continuous renal replacement therapy (CRRT), Peritoneal dialysis, and comparative.' Outcomes: We sought to explore the studies' findings by comparing the mortality rates among the three broad categories of dialysis. Therefore, we aimed to compare mortality rates in CRRT vs. Hemodialysis, mortality Rates in CRRT vs. PD, and mortality rates in patients with PD vs. HD. Results: Fifteen studies were narrowed down from the study search and were placed into three categories: PD vs. CRRT (4), PD vs. HD (5), and CRRT vs. HD (6). For the three outcomes, none recorded statistically significant differences in mortality rates between the patient categories (p= 0.92, 0.009, 0.22). Conclusion: Like other interventions for patients with chronic kidney disease, dialysis is associated with detrimental effects caused by the inflammatory response and worsening progression of the condition. Mortality is a common complication among dialysis patients, independent of modality, based on the lack of statistically significant differences between the three groups.
