Yes, diabetes can potentially contribute to the development of paroxysmal supraventricular tachycardia (pSVT). Diabetes affects the cardiovascular system in multiple ways that may increase the risk of cardiac arrhythmias, including pSVT. The autonomic neuropathy that commonly develops in diabetic patients can disrupt normal heart rhythm regulation by affecting the sympathetic and parasympathetic nervous systems. Additionally, diabetes accelerates atherosclerosis and coronary artery disease, which can create substrate for arrhythmias. Electrolyte imbalances, particularly potassium fluctuations that occur with poor glucose control or diabetic ketoacidosis, can trigger cardiac rhythm disturbances. Chronic inflammation and oxidative stress associated with diabetes may also damage cardiac tissue and conduction pathways.
According to the most recent study 1, paroxysmal supraventricular tachycardia (PSVT) is a common condition that affects 168 to 332 per 100,000 individuals, and its diagnosis and management are crucial to prevent adverse outcomes. The study highlights the importance of tight glucose control in diabetic patients experiencing pSVT episodes, alongside standard pSVT treatments. Maintaining HbA1c levels below 7% can help reduce arrhythmia risk, while regular cardiac monitoring may be warranted in diabetic patients with additional risk factors for arrhythmias.
Some key points to consider in the management of pSVT in diabetic patients include:
- The use of vagal maneuvers, such as the modified Valsalva maneuver, as a first-line treatment for hemodynamically stable patients 1
- The effectiveness of intravenous adenosine in converting pSVT to sinus rhythm, with a success rate of 91% 1
- The importance of catheter ablation as a highly effective and recommended treatment for preventing recurrence of pSVT, with a success rate of 94.3% to 98.5% 1
- The potential role of calcium channel blockers, β-blockers, and antiarrhythmic agents in the long-term management of pSVT, although the evidence for their effectiveness is limited 1
Overall, the management of pSVT in diabetic patients requires a comprehensive approach that takes into account the patient's underlying cardiovascular risk factors, as well as the potential consequences of poor glucose control on cardiac rhythm regulation. Tight glucose control and regular cardiac monitoring are essential components of this approach, alongside standard pSVT treatments 1.
