For a patient receiving metoprolol tartrate twice daily, check heart rate, blood pressure, symptoms, and rhythm/clinical status before each dose. Follow the prescriber’s order and your facility’s hold parameters first.
Common adult nursing hold parameters:
| Finding before dose | Usual action |
|---|---|
| HR <50 beats/min | Hold and notify prescriber, especially if new or symptomatic. Some units use <60/min as the ordered hold threshold. |
| SBP <90 mmHg | Hold and notify prescriber. |
| Symptomatic hypotension | Hold if dizziness, syncope, altered mentation, cool/clammy skin, weakness, or poor perfusion, even if a number is borderline. |
| New/worsening heart failure | Hold and urgently assess if pulmonary edema, increasing dyspnea, new crackles, rapid weight gain, or marked peripheral edema. |
| Heart block or significant bradyarrhythmia | Do not give in second- or third-degree AV block without a functioning pacemaker, or in sick sinus syndrome unless paced. |
| Shock/poor perfusion | Hold and seek urgent medical review. |
A commonly used practical order is: hold for HR <50/min or SBP <90 mmHg, but a patient may have individualized targets. For example, someone taking it for atrial fibrillation may need a different threshold than someone receiving it for hypertension.
The metoprolol label lists severe bradycardia, systolic BP <100 mmHg, cardiogenic shock, decompensated heart failure, and higher-degree heart block among contraindications in the acute-MI setting; it also emphasizes titration according to heart rate and BP. The heart textbook source identifies significant bradycardia as HR <50/min and hypotension as SBP <90 mmHg. See the DailyMed prescribing information and Fuster and Hurst's The Heart, p. 2563.
Do not routinely stop long-term metoprolol abruptly without a clinician’s plan, because sudden withdrawal can worsen angina or precipitate ischemic events.

ventricular paced rhythm ECG pacemaker spike wide QRS discordant ST T wave
Finding Sources
This looks most like a ventricular paced rhythm on a bedside ECG monitor.
Why:
- There is a narrow, tall pacemaker spike just before each beat.
- Each spike is followed by a wide QRS complex, consistent with ventricular capture.
- The ST-T wave direction looks opposite the main QRS direction, which can be a normal secondary repolarization change in paced rhythms.
It may be dual-chamber pacing if the smaller wave before the ventricular spike represents an intrinsic or atrial-paced P wave, but this single monitor lead cannot confirm the pacing mode.
A photo of one lead cannot reliably assess ischemia or all pacemaker function. If this is new, there are symptoms, the rate is abnormal, or spikes are not consistently followed by QRS complexes, obtain a 12-lead ECG and have the rhythm reviewed promptly. Rosen’s Emergency Medicine notes that a wide QRS immediately after a pacing spike is typical of ventricular pacing, often with a left-bundle-branch-block-like morphology.
