One beat, up close
Most of what goes wrong
shows up here first.
Most nurses learn rhythms in one class and labs in another, then never put the two side by side. That gap is where Kristina teaches. Match the potassium to the T wave and the magnesium to the QT, and a borderline result stops being a number on a screen. It becomes a warning with a clock on it.
The practice
The long version runs
twenty-eight years.
The short version
is cardiac.
Kristina M. McGahan has been a nurse since 1998. Today she works as a nurse consultant, a burnout recovery coach, and the clinical nurse coordinator for a cardiac care unit. The last of those keeps her on the floor.
Cardiac and telemetry is the core of it, with progressive care, medical‑surgical and cardiovascular services around the edges. Somewhere in those twenty-eight years she also became the person hospitals hand their new nurses to. She has precepted, taught, written orientation programs and led.
Mind Over Matter: Nursing Recovery Summit
She built this
because she burned out first.
Kristina founded the Mind Over Matter: Nursing Recovery Summit after her own run at professional burnout. It is a coaching program, not a conference. It addresses burnout and emotional exhaustion through nervous-system-based work, for nurses carrying stress and trauma they have had nowhere to put.
She is NLP certified and a certified life coach as well as an RN, which is the part that matters here: she is not a therapist and does not present herself as one. She coaches nurses across the country through this work now, and intends to widen it.
- Burnout recovery coachingFor the nurse who is still clocking in and no longer sure why.
- Nursing educationTelemetry and cardiovascular teaching, pitched at the bedside rather than the lecture hall.
- ConsultingClinical care, leadership, and how a unit actually runs.

What Every Nurse
Must See Before a Code:
Telemetry Secrets
Written for the nurse who has the monitor, the labs and no time. It covers what to look for before a patient codes, and how to chart it so the note still holds up months later.
- Rhythm strips and case studiesReal strips, worked through the way you would at the bedside.
- Flowcharts and escalation templatesWhat to do next, and who to call, before it becomes a code.
- Documentation guidanceCharting that survives being read back to you a year later.
- Electrolytes, AV blocks, early declineThe changes that show on the monitor before they show in the patient.
For new graduates, for nurses who have been doing this twenty years, and for the educators teaching both.

From the nurses who read it
“Finally, someone gets it. This isn’t another dry ECG manual. Kristina connects the dots between labs and rhythms in a way that actually sticks.”
Michelle R.Cardiac RN
“The magnesium chapter changed my practice. I never realized how often low Mg makes K+ replacements useless. Now I demand both get checked together.”
Carlos M.ED RN
“The legal chapters hit home. I used to chart ‘MD aware’ like everyone else. Now I write exact times, what I said in SBAR, and orders received.”
Michael H.Night shift charge nurse
“As a newbie, I’d panic over every weird rhythm. This book taught me to ask ‘What’s the story?’ instead of just memorizing strips.”
Kate W.New grad, med-surg telemetry
“I’m buying copies for my whole orientation group. The ‘Thinking Nurse’ chapter is what new grads actually need, not more task lists.”
