Holter Monitor technology remains one of the most widely used ambulatory ECG tools for detecting intermittent arrhythmias, evaluating symptoms, and assessing treatment efficacy over 24 hours or longer. This session provides a structured overview of recording systems, setup, interpretation, troubleshooting, and clinical application, mirroring the depth expected from a focused Holter Monitor track within a broader cardiology conference, where case discussions highlight how advanced Holter monittroring satergies can transform rhythm evaluation in daily practice.

The description begins by reviewing core components of Holter monitoring, including electrodes, leads, wearable recorders, storage systems, and analysis software. Participants will understand how continuous multi-lead recordings capture arrhythmias that standard twelve-lead ECGs miss because of their brief sampling window. Use cases include palpitations, syncope, dizziness, chest discomfort, suspected silent atrial fibrillation, rate-control assessment, pacemaker function review, and post-ablation surveillance.

A major focus is placed on obtaining high-quality recordings. Attendees will learn how to select appropriate lead configurations, prepare the skin, position electrodes to minimize artifact, and educate patients about daily activities, showering, and diary completion. The session explains how to identify and correct common problems such as loose electrodes, motion artifact, myopotential interference, and poor contact in hot or humid climates.

The interpretive portion of the session guides participants through step-by-step analysis of Holter data, from basic rhythm identification to advanced pattern recognition. They will learn to quantify supraventricular and ventricular ectopy, classify tachyarrhythmias and bradyarrhythmias, evaluate pauses and blocks, and link symptom events to rhythm strips. The role of heart-rate variability metrics in risk stratification and autonomic assessment is also addressed.

Extended and alternative monitoring options are compared, including seven-day Holter, patch monitors, event recorders, mobile cardiac outpatient telemetry, and consumer wearables. Participants will understand when to escalate beyond standard Holter monitoring, how to choose the right modality for symptom frequency, and how to streamline workflow in busy clinics.

Real-world case vignettes illustrate how timely Holter monitoring can uncover previously unrecognized atrial fibrillation in stroke patients, reveal nocturnal pauses associated with sleep apnea, or document nonsustained ventricular tachycardia prompting further risk stratification. Practical templates and structured reporting examples help standardize interpretation across team members, ensuring that Holter data consistently informs decisions about medication adjustment, ablation referral, or device implantation in a safe, evidence-aligned manner.
