To understand cardiac implantable electronic device (CIED) management, the clinician requires a foundation of information regarding CIED purpose, design and function, as well as experience in interpreting CIED output, i.e., electrical assessment of the system, programmed parameters, electrograms, and markers. In addition, one must be able to correlate and interpret the accompanying electrocardiographic tracing with the patient's clinical presentation.For students of CIED management, be they beginners in the field or more advanced, there is always an appreciation for case studies, i.e., real-world examples of managing a specific device-related issue.To this end, this workbook of 61 device management case studies has been prepared by six talented RN Device Specialists and three physicians involved in the Heart Rhythm Service practice at the Mayo Clinic in Rochester, Minnesota. Included in the case studies are examples from pacemakers, ICDs and CRT devices, illustrating interpretation and management of a variety of device behaviors, some with abnormal function that requires diagnosis and management approach, and others that display appropriate behavior of a specific device algorithm that may be confusing for the CIED student. ~David L. Hayes, MD, and the contributors – adapted from the Preface.

PATIENT:

An

82-year-old 

patient 

with 

a

history 

of

chronic 

atrial 

fibrillation 

receives 

a

single-

chamber 

pacemaker 

for

symptomatic 

bradycardia. 

At

a

routine 

in-clinic 

follow-up, 

the

EGM

tracing 

(

Figure

)

was

obtained.

ANALYSIS

1.

The

first 

two

QRS

complexes 

share 

the

same 

wide 

QRS

morphology 

and

represent 

a

true 

ventricular 

paced 

beat.

2.

The

third 

complex 

is

not

the

same 

as

the

first 

two

QRS

complexes, 

i.e., 

the

QRS

is

nar-

rower, 

but

significantly 

different 

than 

the

single 

ventricular 

sensed 

beat 

seen 

later 

in

the

tracing 

[4]. 

This 

represents 

a

ventricular 

fusion 

beat 

(fusion 

of

paced 

and

conducted 

wavefronts).
