Te prevalence of this comorbidity is signitant. Studies estimate that approxiately 10- 15% of patients with hypertyroidism also have diabetetes, and the bidirectional relationship between tyreid dysfunctionion and glucose meanism mean that untreaved hypertyroidiism can worsen glycemic control, while poorly controlle thee leade diabetetes can complicate tyreid regulation.

Monitoring Strategies: A Systematic Approach

Given the heightened risk profile, monitoring mutt be complessive and coordinated. Below are key contrigents of an effective surveillance plan, arranged frem basic to advanced.

Basic Vital Signs andd Symptom Tracking

Patients should be educate to samo-monitor for palpitations, disgnea, chest discoult, and leg swelling. A providentom diary caste capture paroxysmal events that may not appear on single ECGs. Consider using smartphone-based heart rate monitoring apps with ECG capilities for patients with paroxysmal toms.

Elektrokardiografia (EKG)

A 12- lead ECG powinien być perfomed at baseline and repeated when enever there is a change in sumptoms, initiation of antiarytmic or tyreidid-directed therapy, or every 6- 12 months in stable patients. Ambulatoryy monitoring (Holter or event direcoder) is indicated for unexplained palpitations or syncope, and can exicent silent AF in diabepitic patients who may lack typical directoms.
