Background:
The Reveal LINQ™Insertable Cardiac Monitor (ICM) or Implantable Loop recorder (ILR), is a miniaturized, subcutaneous, single lead, electrocardiographic monitoring device which has been extensively used in the differential diagnosis of unexplained syncope and palpitations in adults.
Patient Description:
We describe an asymptomatic 20-month-old boy, noted to have incidental bradycardia on routine examination and in whom Holter monitoring revealed complete heart block (CHB). Over 1 year, the longest recorded pause lengthened from 1.8 seconds to 3.6 seconds.
Results:
The Reveal LINQ™ ICM was inserted for long-term monitoring of the CHB. The device will record the electrocardiogram (ECG) continuously for up to 3 years, freezing in its memory any significant arrhythmic events. This will enable the diagnosis of the longest pauses, confirm whether they are lengthening over time and assist with the decision of pacemaker implantation.
Conclusion:
The Reveal LINQ™ ICM is much smaller than the conventional loop recorder and has been shown to be ideal for close monitoring of asymptomatic yet potentially dangerous arrhythmias in young children.

Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

01:19Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
01:13The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
01:29Cardiac Cycle
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...
