GETTING THE MOST FROM YOUR ECG
The ECG tracing is a valuable diagnostic tool, and their interpretation can be a
challenging task for the clinician and staff. However, with some simple study, the ECG
will be an indispensable clinical parameter.
Some recommended indications for the use of the ECG include:
¾Any animal with a heart murmur or arrhythmia detected with a stethoscope.
¾Any animal with episodes of weakness or fainting, exercise intolerance, or
sudden changes in activity level..
¾A hypothyroid dog or hyperthyroid cat.
¾Any animal with hypotension or hypertension.
¾Any patient being treated for congestive heart disease should have follow-up
tracings as part of maintenance and control of the disease.
¾Electrolyte imbalances such as Addison’s disease.
¾Breeds with predispositions to heart disease, such as Persian cats and
Doberman Pinschers.
¾Geriatric exams can be greatly enhanced by the addition of a LEAD II rhythm
strip screening.
Should suspicious tracings exist, then a full 6-lead cardiograph analysis is
recommended.
An ECG recording should always be evaluated in conjunction with complete
patient history, clinical findings, radiographs, blood chemistries including
electrolytes and blood gases, and urinalysis. The recording is not by itself a
complete diagnosis but rather a look at the electrical activity of the myocardium,
that can be affected by many disorders along with artifactual interference.

HELPFUL HINTS FOR GETTING
QUALITY ECG TRACINGS
Use a rubber mat to insulate the patient from a stainless steel table.
Select a quiet or remote area of the clinic for the procedure.
Leave the instrument turned off until the leads are attached and the animal
is calm.
Right lateral recumbency is the standard body position for ECG recording in
dogs and cats.
If respiratory distress is evident, consider recording with the animal standing or
in sternal recumbency.
To obtain the most accurate tracings, care should be taken to avoid undo stress
and minimize the “white coat” effect. Allow the animal to become familiar with its
surroundings.
Establishing contact with the patient is important, especially for the person
administering the ECG.
Consider owner participation in cases of small dogs or cats, or animals that are
especially frightened. Small patients may be placed on the lap of the owner, or
of another technician if it will alleviate stress.
Some dogs will tolerate the procedure much better if standing on the floor rather
than being placed on a table.
Use of sedatives or tranquilizers is not advisable for diagnostic recordings. If
used possible effects on those tracings should be taken into consideration.
Attach electrodes to the skin and moisten with ECG gel or 70% alcohol. When
using alcohol avoid excessive amounts, as alcohol may travel between leads.
Essentially this has the same effect as having electrodes touch each other.

INTRODUCTION
The Jorvet™ Single Channel ECG is a one-channel digital electrocardiograph that
records the 6 most common leads: Lead I, II, III through AVR, AVL and AVF. 4 patient-
comfortable limb leads and a ground are provided. It is equipped with an advanced wide
range thermal-array printing system, single chip 32 bit microprocessor.
FEATURES
¾High resolution built in thermal array printer (8 dot/mm)
¾Installed rechargeable NiMH 12 volt battery will support approximately 50 patient
examinations, depending on length of examinations.
¾Keypad one-touch buttons allow for easy set-up and operation.
¾LED screen is well-lit and easy to read.
¾Lead strips print patient information form (AUTO mode) as well as sensitivity,
paper speed, and filter settings.
¾AUTO and MANUAL modes provide optimal customization for diagnostic
Interpretation.
GROUNDING
The J1010 is grounded during AC operation through the three-prong AC plug.
During battery operation, a grounding wire (included) should be connected to the
ground site on the back of the unit.

BATTERY OPERATION
The J1010 has an installed maintenance-free 12 volt NiMH rechargeable battery.
Please allow 10 hours to completely recharge the battery if drained fully. Recharge in
the AC operation mode: flip on the power switch at the back panel of the unit. Do not
press the ON/OFF button. DO NOT charge the battery for more than 24 continuous
hours. The unit may be left plugged in, but the power switch must be off to prevent
damage to the battery.
Battery charge status is indicated on the LED tracing screen (battery mode only).
Indicator light flashes green on keypad when charging and turns to a solid green when
fully charged. Turn the power switch off at this time (Power switch on back panel of
unit solely operates battery charging).
To operate solely on battery turn power switch on back panel to OFF (battery icon
should be illuminated in upper right corner of screen). If battery icon is white battery is
fully charged and ready to use, battery icon will empty as battery is depleted.
The cardiograph will turn itself off after 5 minutes of non-use. Press ON/OFF to
resume. During long term storage or extended periods of non-use, recharge the battery
every 6 months.
Always check battery level on the screen before running on battery power.
LOADING THE ECG PAPER
Depress the button on the left side of the machine to open the door of the paper
cabinet, and lift door off. Load paper printed side down and replace the door with the
rubber roller sitting on top of the paper.
Avoid slack in the paper tension and align the paper straight with the door edge.
Adjust paper position as necessary if printing is off center. PAPER? alarm will appear
on screen until paper is replaced or the situation is remedied.
